How Does RNA Extraction Homogenization Work? 

Posted by Deb Shechter on Jan 25, 2018 11:30:00 AM

RNA extraction homogenizationMany people are familiar with the term “DNA,” which is the hereditary material in humans and almost all other organisms. Officially named deoxyribonucleic acid, it a molecule that carries the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses.

Not as well known outside the field of science is RNA or ribonucleic acid. RNA, a type of nucleic acid containing only one strand (DNA is primarily double-stranded), provides the link between the genetic information through protein synthesis. Procuring high-grade RNA, which is accomplished through a process called RNA extraction (or isolation), is the first step for a multitude of molecular techniques often utilized in gene expression including microarray analysis, real-time polymerase chain reaction (PCR), digital PCR, northern analysis and cDNA library construction.

RNA Extraction

Using a powerful chaotropic salt solution, RNA extraction purifies RNA from biological samples by quickly disrupting cells or tissue to release the nucleic acids from the cells. These released RNAs are valuable in providing details on which genes are expressed (used to make products), to what degree the genes are active, how they work to regulate each other via small, regulatory RNAs and which structural RNAs (i.e. rRNAs, mRNAs and tRNAs) are produced.

RNA extraction can be very challenging due to the difficulty of isolating RNA that is intact. This is in large part because of ribonuclease (RNase) enzymes found in cells, enzymes which are copious in the environment and can swiftly degrade RNA. Therefore, it’s vital that it be done cautiously and in a timely manner.

Homogenization – Organic RNA Extraction

The disruption of cell and tissue samples, often achieved by homogenization, is a required part of extracting RNAs and preventing their degradation. In fact, samples aren’t guarded from RNA degradation unless they are entirely homogenized. Although homogenization is especially functional for use with soft tissues, the method used should be based on the sort of cell or tissue. For instance, plant and animal tissues, yeast and bacteria typically require more exacting disruption methods. Either way, the sample or tissue should be kept frozen until it is ready to be homogenized.

Utilizing homogenization for RNA extraction is especially beneficial because it enables processing to be effectively and repetitively processed in only seconds, thereby eliminating heat production. Its force and high pressure produce consistent and uniform samples, and it can process both small and large samples. Plus, homogenizers are scalable and compatible with many sample types, including those with tough cell walls.

Chemical Methods for Cell Disruption

Posted by David Shechter on Jan 16, 2018 11:30:00 AM

cell disruptionCell disruption is used throughout many industries, from cosmetics and pharmaceuticals to food and biotechnology. As a method or process employed to release biological molecules or other materials from inside a cell, these industries commonly utilize it to study intercellular materials or use the materials located inside a given cell. It can be achieved through a range of methods and technologies, either mechanical or non-mechanical.

The method of cell disruption selected depends on the product, scale and cell type and must obtain the necessary components effectively and reliably without disturbing any of its components. Though high-pressure homogenization is the most common procedure for cell disruption, chemical methods including osmotic lysis, surfactants and chaotropic agents also are prevalent. In this blog, we’ll go into more detail on each of these methods.

Osmotic Lysis

In osmotic lysis (or shock), cells are suspended in a hypotonic extracellular environment, usually a dilute sucrose solution, causing them to take on water, swell and burst. It’s often applied to lyse mammalian blood cells and for RNA extraction, although it is sometimes used to disrupt microbial cells. Due to its low efficiency, however, it is one of the less commonly used chemical methods of cell disruption.


Surfactants (surface acting agents), often called detergents, are compounds that lower surface tension and disrupt the distinct interface between hydrophobic and hydrophilic systems. Their hydrophilic head and hydrophobic tail enable them to insert into and then disperse biological membranes. They are used at fairly low concentrations, and in order to disrupt bacterial cells, they must be used with lysozyme.

Detergents used for disrupting cells are divided three categories depending on their electrical charge: anionic, cationic and non-ionic. All three directly damage the cell wall or membrane, although the best detergents can lyse cells and solubilize proteins. Surfactant cell lysis may be used with ultrasonic processing in order to facilitate disruption.

Surfactants aren’t used for cell disruption more often because they denature proteins in the process and have different impacts on biological systems depending on which detergent is utilized and what its concentration is. No one detergent can be employed for all applications, and some of those selected may disturb downstream processing steps further in the process.

Chaotropic Agents

Chaotropic agents such as urea, guanidine and sodium iodide are capable of bringing some hydrophobic compounds into aqueous solutions by disrupting the structure of water, making it a less hydrophilic environment, and weakening the hydrophobic interactions among solute molecules. Used in very high concentrations, they are like surfactants because they break non-covalent interactions. Unlike surfactants, though, chaotropic agents disrupt the weak interactions between molecules and are sometimes used with detergents to denature and emulsify biological systems.

These techniques are usually only viable at laboratory scale due to increased consumption of energy, chemicals and water and can be very costly for use in large-scale manufacturing. Conditions during the chemical disruption process aren’t always uniform among samples, making it a risky proposition. In addition, some components may cause the denaturation of protein, resulting in a damaged end product.

High-pressure Homogenization

In high-pressure homogenization, a cell disruption method most often used for soft, solid tissues, samples are forced through a narrow space while pressure is applied to them. As the temperature increases, so does the rate of cell disruption. Although they can be used for small batches, high-pressure homogenizers are scalable and can easily adapt to different sample sizes to accommodate increased demand. They not only provide a high level of disruption efficiency but also can be used for the recovery of recombinant proteins.

Suspension vs. Colloid: How Do They Differ?

Posted by Tal Shechter on Dec 20, 2017 11:30:00 AM

suspension vs colloidAs we’ve outlined in recent blogs, homogenization is a process utilized for particle size reduction and works by employing mechanical force to break down particles or droplets in a liquid into smaller and more uniform sizes. The result of homogenization is a dispersion, wherein fine particles of one substance are scattered throughout another substance. Furthermore, dispersions are able to be classified by the sizes of these scattered particles: solutions, suspensions and colloids. In this blog, we’re focusing on the difference between suspension and colloids.


Simply defined as a heterogeneous mixture of two substances in which one is dispersed into the other, suspensions involve particles larger than those found in solutions, typically over 1,000 nm. The bigger particles of a suspension usually settle or separate out of a mixture upon standing or are able to be filtered out, although not through filter paper. Gravity is able to pull the visible particles in a suspension down if undisturbed, and they will stay that way unless being actively mixed. Examples of suspensions include oil and water, dust or soot in air, sand and water and muddy water.


Although a heterogeneous mixture of two substances like suspensions, colloids involve particles from 1-1,000 nm that do not separate upon standing and cannot be separated by filtration. The particles in a colloid land in size between those in a solution and a suspension and may be solid, liquid or gas. The two parts in every colloid mixture are its particles and the dispersing medium, and the particles are spread evenly in in the medium, which can also be solid, liquid or gas. Examples of colloids are foams (shaving cream, Styrofoam), gels (gelatin, jelly), emulsions (mayonnaise, lotion), aerosols (fog, insecticide spray, smoke) and sols (shampoo, gemstones).

Even though the particles in a colloid are very small in size, they can be seen through a process called the Tyndall Effect, the effect of light scattering in colloidal dispersion while showing no light in a true solution. This effect is used to determine whether a mixture is a true solution or a colloid.

Colloid mills, like homogenizers, are able to process particle reduction formulations, although each is preferential for certain applications. They are best used for samples comprised of solids immersed in a liquid suspension or a liquid suspended in another liquid because they can enhance the stability and/or reduce the size of suspended particles.


In summary, following are some of the main differences between a suspension and colloid:

  • Particles in a suspension are usually more than 1,000 nm, while those in a colloid range from 1-1,000 nm.
  • Unlike those in a suspension, particles in a colloid do not separate when sitting still.
  • The particles in a suspension may be separated by filtration unlike those in a colloid.
  • Colloids are able to scatter light, but suspensions cannot transmit light.
  • Particles in a suspension can be seen by the naked eye, but those in a colloid must be viewed using a light microscope.

Food Homogenization 101: What You Need to Know

Posted by David Shechter on Dec 13, 2017 11:30:00 AM

food homogenizationThe food and beverage industry continues to expand and diversify, especially as consumers look for more healthful products that fit both their lifestyle and budget. Companies must find ways to create and market products to differentiate them from their many competitors while ensuring their goods have the taste, freshness and nutrients on which customers have come to rely.

A common method food processing and manufacturing companies utilize to efficiently, cost-effectively and safely produce their goods is high-pressure homogenization. It not only reduces particle size through forces including high pressure, shear, turbulence, acceleration and impact but also allows for the stable and consistent production of emulsions, suspensions and other commodities that necessitate a liquid suspended in another liquid.

Though one of the most well-known uses of homogenization in the food and beverage industry is for milk, it is also widely used in the manufacture of sauces, spreads, salad dressings, fruit juices and concentrates, fish and meat paté, sweeteners, baby food, egg product, other dairy products and more. The homogenization pressures used for these products typically range between 20 and 60 MPa, but some homogenizers can reach pressures of up to 400 MPa. This magnitude of pressure leads to microbial and enzyme inactivation, which enhances the safety and shelf life of perishable foods while reducing the thermal effects on the foods’ functional and sensory qualities.

Once a company achieves its ideal product, the product needs to be reproduced on a larger scale without losing the characteristics that make it desirable by customers. If it doesn’t offer the same taste and texture on a regular basis, the manufacturer may not only lose customers and their funds but also obtain a damaged reputation.

Food homogenizers help deliver a product with uniform texture, flavoring and taste through a scalable and cost-effective process that allows for a longer period of freshness than food comprised of larger particles. The smaller the particles, the longer the structure of the product can be maintained. Food homogenizers’ ability to use pressure instead of heat preserves critical nutritional components naturally found in a food, enabling them to be available for consumption.

Although high-pressure homogenization may potentially replace thermal methods of food preparation, it does not effectively produce solid foods or ones formed from large particles. Also, because it uses force instead of thermal action, homogenization does not sterilize foods or beverages, requiring it to be accomplished through a separate process.

BEE International: Help in Finding the Best Food Homogenizer

The key to purchasing the right food homogenizer for your business needs is selecting one that can achieve consistent particle size distribution on a scalable basis. At BEE International, our equipment can engineer particle sizes at or below 100 nm, a benefit favorable for most any product in the food and beverage industry.

Liquid Mixers vs High Pressure Homogenizers: Which Is Right for You?

Posted by Deb Shechter on Dec 6, 2017 11:30:00 AM

liquid mixersIt’s not uncommon for terms or even buzzwords in various industries to be similar but have different applications. For example, in the healthcare industry, electronic medical and electronic health records may sound the same. However, electronic medical records (EMRs) are a digital version of the paper charts in the clinician’s office that contain the medical and treatment history of the patients in one practice, while electronic health records (EHRs) focus on the total health of the patient, provide a broader view on a patient’s care and are designed to share information with other healthcare providers.

Similarly, though the terms “liquid homogenization” and “high-pressure homogenization” appear comparable, each has its own characteristics and primary uses. Homogenization in general can be defined as the reduction of particle size of any given molecule and is a process utilized often in the pharmaceutical, biotech, cosmetic and pharmaceutical industries. Its benefits include more even particle distribution, improved texture and enhanced appearance and taste.

Liquid homogenization, achieved by using a liquid mixer, and high pressure homogenization offer similar outcomes yet use distinct processes. The mixing processes and mixer designs chosen are determined by the nature of the materials to be mixed. Essentially, the type of product you select for your laboratory depends on its downstream applications and the cell types being used. 

In this blog, we’ll describe the differences between liquid and high-pressure homogenization and list pros and cons of each to help you decide which one is best suited to your business needs. Whichever you choose, it’s important that it has the flexibility to meet the various needs of a laboratory. 

Liquid Homogenization

Widely used for cell disruption of cultured cells and small sample volumes, liquid homogenization requires a sample to manually be forced through a narrow space, thereby shearing membranes and decreasing particle size. There are three most common types of liquid mixers used: the Dounce homogenizer (used for gently lysing single cell suspensions), Potter-Elvehjem homogenizer (used with delicate tissues) and the French press (used for small sample volumes). In addition to being suitable for operation at higher temperatures and easy to maintain, liquid mixers offer enhanced repeatability and a lower power requirement. Nevertheless, the throughput from all three models is fairly low, and they may not provide enough scalability. 

High-pressure Homogenization 

Utilized for numerous products from the chemical and biotechnology industries and products such as pharmaceutical tablet coatings, vaccinations and creams, high-pressure homogenization uses multiple mechanical forces (such as turbulence, cavitation and shear) along with intensive pressure to achieve micronization and membrane lysis. Similar to liquid mixers, high-pressure homogenizers work by forcing cell suspensions through a very narrow channel under pressure. Unlike the manual requirement of liquid homogenizers, though, high-pressure units run automatically and are often made to be scaled from laboratory experimentation to manufacturing.

Benefits of high-pressure homogenization include an increased rate of dissolution, ease of operation, cost and time effectiveness, consistency in composition of products, greater stability of final products due to a stable emulsion and upgraded scalability and repeatability. High-pressure homogenization also has the ability to reduce particle size to levels that are not achievable by most other mixing processes. Because they tend to be large and very heavy, high-pressure homogenizers are typically used for large volume processing and consume more power than liquid mixers. They sometimes require more complex cleaning, cannot handle large particles or high-fiber materials and aren’t the most suitable for high temperature materials. 

BEE: The Industry Leader in High-Pressure Homogenizers

BEE International offers a wide variety of high pressure homogenizers to meet the needs of virtually any industry. Unlike liquid mixers, our homogenizers are suited for large samples and offer large throughputs, making them ideal for laboratory, pilot plant and even industrial use.

How Do Inline Mixers Work Differently Than High-pressure Homogenizers?

Posted by Tal Shechter on Dec 1, 2017 11:30:00 AM

inline mixersWhen they hear the term “homogenization,” many people think of milk. In fact, one of the first applications of homogenization came in the processing of milk. Derived from the Greek word “homogenos” (homos meaning same and genos meaning kind), it is defined as the process of reducing the particle size of an object and is also known as micronization.

Homogenization works by forcing a sample through a narrow space through multiple mechanical forces, thereby producing a stable and consistent product. Easily scalable, it is used by multiple industries, including pharmaceutical, biotech, cosmetic and food, in order to optimize their finished product.

Under the umbrella of homogenization lie two different methods: inline mixing and high-pressure homogenization. Read on to learn the differences between how the two work and advantages associated with each.

Inline Mixing  

Positioned within the production line and aligned with the flow of product, inline mixers consist of a stationary stator and an inside rotor that turns at high speeds. The rotor–stator device is contained in a casing with an inlet at one end and an outlet at the other, and the rotor is driven through a seal. Mixing occurs when a sample is drawn in through one of the mixing heads while the blades rotate and is then expelled at a high velocity through an opening in the stator. The inline term comes into play around the mode of sample entry into the mixing chamber.

Inline mixers feed and output material in a continuous stream, allowing material to often be perfectly hydrated, emulsified or homogenized in a single pass. They differ from other types of homogenization wherein large amounts of ingredients are mixed in a standalone unit before going through the homogenization process. Designed to handle all types of tasks, including emulsifying, suspending, dispersing, blending and more, inline mixers are suitable and useful for applications where larger quantities are needed for production and continuous processing and homogenization is needed during the manufacturing process. In addition to being faster than their high-pressure counterparts, they allow for a more controlled and continuous mixing environment, improve yields, use less energy and increase capacities.

High-pressure Homogenization

Whereas inline mixers rely on rotor/stator shearing action, high-pressure homogenizers force a sample through a narrow space using force and high pressure, thereby reducing particle size or lysing cells. They consist of a high-pressure pump and a disruption unit which enable a continuous homogenization. The higher the amount of energy applied during the homogenization process, the smaller the particle size or the more complete the cell lysis. The pressure along with the action of multiple forces yields impactful results in only one or two passes. Benefits of high-pressure homogenization include consistency in composition of products, greater stability of final products and decreased cost. Also high-pressure homogenizers allow users to set operating parameters - pressure, temperature, number of passes, valve and impingement design and flow rate – for a particular homogenization.

Dispersion Creation

Dispersions, also known as suspensions, consist of solid particles distributed throughout a continuous medium. Examples of dispersions include polymers, petroleum additives, paints, and acrylics. It is important to create high quality dispersions in the production of these items to ensure maximum particle packing, increased conductivity, and improved overall surface quality.  High quality dispersions results in a higher quality end product, which almost always translates to a better bottom line.

Particle Size Reduction Capabilities

When choosing a homogenizer, it is important to choose a high pressure homogenizer that can efficiently and readily decrease particle sizes. This process, also known as micronization, results in smaller particle sizes, which help facilitate easier dissolution, increased product stability, and higher overall quality. This results in increased customer satisfaction as well as reduced costs of production.

How to Pick Out a Homogenizer for Cell Lysis

Posted by David Shechter on Oct 26, 2017 11:30:00 PM

Thinking woman in glasses looking up with light idea bulb above head isolated on gray wall background-603464-edited.jpegCell lysis is commonly described as the process of releasing biological molecules from inside a cell, and is a powerful method utilized in a variety of manufacturing industries, including pharmaceutical, cosmetic, biotech, and R&D settings. With the popularity of this technology, more and more industry professionals are seeking out homogenizers to assist with the process of cell lysis. However, before settling on the right homogenizer for the job, it is important to understand more about cell lysis and what it entails.

During the process of cell lysis, in order to thoroughly study and analyze the behavior of molecules, the cells that produce the molecules in question must be disrupted. Disruption of cells can be achieved in numerous ways, including cryopulverization, nitrogen decompression, or through using a homogenizer.  Each method comes with varying degrees of complexity, ease, and success.

Cryopulverization is one way of accomplishing cell lysis, and is most often used for cellular samples with a tough outer matrix, such as cartilage, connective tissue, or seeds. In this method, the samples are reduced to a powder through the use of liquid nitrogen and impact pulverization. This method, while successful, is often time consuming and expensive.

Nitrogen decompression, as the name suggests, uses large quantities of nitrogen to achieve cell lysis. In this particular method, nitrogen is dissolved in the cell under very high pressures. When the pressure is released, the nitrogen violently escapes the cell, causing disruption and breakage of the cell walls. While nitrogen decompression is successful in disrupting certain types of cells – plant cells, bacteria, and other fragile cell types are most receptive to this treatment – it has not been proven to be effective in disrupting cells with tougher outer matrices, such as yeast, spores, and fungus.

Homogenization is arguably the most widely used method of cell lysis, especially for small volumes of cells and/or cultured cells. This method involves the use of shearing force on the cell. This is achieved by forcing the small cell through an even smaller sized orifice. This removes the outer layer and lyses the cell.

BEE International offers a number of high-quality homogenizers to meet the needs of any industry when it comes to the process of cell lysis and disruption. Our laboratory grade homogenizers include the Nano DeBEE, Micro DeBEE, and Mini DeBEE – all three are easy to use, offer consistent and reliable results, and easily scale up for full scale production. In addition, our homogenizers offer maximum experimentation capabilities, the ability to change flow, pressure, shear, and impact settings, and offer high pressures up to 45,000 PSI for maximum effectiveness with cell lysis and disruption.

Contact us today to learn more about how our line of homogenizers can help you meet your production needs. We are more than happy to help you get started on your next big project, and to help you choose the right homogenizer for the most efficient and effective cell lysis.
