      APPLICATIONS

      Cell Disruption


      Explore Microfluidics’ high efficiency technology for breaking cells to capture the intracellular content integrity - with easy downstream purification.

      Cell disruption is the process of breaking cells to recover and maintain the intracellular content integrity with high efficiency.

      As cells are harvested and produced containing molecules or particles such as proteins or viruses, they must be lysed to capture the intracellular contents of interest if they are not extracellularly secreted.

      YOUR CHALLENGES

      Key Challenges for Cell Disruption

      From yeast to mammalian to algae cells, finding a single technology capable of lysing a variety of cell types can be difficult.

      In cell lysis, intracellular content can be temperature sensitive so introducing temperature increases may often damage the material. In addition, any excessive forces can denature the contents and prohibit high rupture rates.

      Separating the proteins of interest from cell debris downstream is also challenging.

      HOW WE CAN HELP

      Resolving Cell Disruption Processing Issues

      Microfluidic technology addresses today’s cell disruption challenges by achieving two efficient methods to lyse cells with minimal time and waste.

      Microfluidics achieves the highest levels of cell rupture and product recovery for all cell types through its ability to supply constant, controlled shear rates.

      The resulting large cell membrane fragments make downstream processing easy.

      Efficient cooling ensures proteins stay intact even with high-pressure processing. Protein yields are high.

      Effective Solutions for Cell Disruption With Microfluidizer® Technology


      Cell disruption is the method or process for releasing biological molecules from inside a cell. Utilizing these intracellular contents (proteins, organelles, DNA/RNA, enzymes and Adeno-Associated Virus (AAVs) Vectors for Gene Therapy Applications) which are found and/or grown inside cells is the next generation for drug development.

      For cells that do not secrete these intracellular contents, it is vital to lyse the cell to liberate these contents. During this process, it is important to prevent denaturing of these intracellular components by the unnecessary elevation of temperature or excessive shear rates.

      Our Microfluidics processors effectively rupture a variety of cell types which require different levels of shear — including bacterial, mammalian, plant, insect, fungi, algae and yeast cells — whilst ensuring high protein recovery. They are tough on cell walls but gentle on the intracellular contents.

      RESULTS

      Cell Disruption Examples

      Microfluidics processors provide many demonstrable advantages over all other cell disruption methods and equipment - for both lab and production volumes.

      Key Advantages of Microfluidizer® Technology for Cell Disruption

      Highest Protein Integrity Recovery

      Precisely controlled shear rates enable our customers to use the minimum pressure required to rupture the target level of cells while keeping proteins intact. Compared with other cell disruption techniques, our processors yield several times the amount of recoverable, usable protein.

      Repeatability

      Microfluidics differentiates itself from its competition in its unparalleled ability to achieve superior, repeatable results. The fixed geometry Interaction Chamber™ ensures consistent, repeatable processing. By maintaining the same processing conditions, results are duplicated batch-to-batch.

      Efficient Cooling

      Cooling is extremely important in cell disruption because cell contents are typically temperature-sensitive. Immediately after rupturing, the heat exchanger minimize the amount of time the sample experiences elevated temperatures and the lower temperatures combined with shorter processing times result in reduced denaturing and increased yields.

      Ease of Use

      Microfluidics’ processors were designed with convenient homogenization of cells and productivity in mind — that’s why they are simple to operate and easy to clean. Customers appreciate how little maintenance is required, especially when compared to high-pressure valve homogenizers that have valves that need to be disassembled and cleaned manually, which is important especially in a multi-user environment to limit cross-contamination.

      Simple Downstream Processes

      Our technology breaks cells gently yet efficiently, resulting in large cell wall fragments. The large fragments are easier to separate from the much smaller cell contents. Filtration times are shorter and the need for centrifugation is reduced.

      Pressure and the number of passes can be set to shear DNA if desired. Shearing the DNA makes downstream pipetting of small volumes of cell lysate simpler and more accurate.

      Processes at a Constant, Controlled Shear Rate

      Processing at constant pressure and shear rates ensures that all cells receive the same amount of energy input. With sonication, cells closer to the probe receive exponentially more energy than cells farther from the probe; batch-processing methods provide little control of energy uniformity to each cell. Some cells remain unbroken, others die or the intracellular contents denature due to the uncontrolled temperature rise of sonicator probes. Monitoring the temperature of a volume of cells cannot tell you what has happened to the majority of cells in a sample. This is why Microfluidic processors give higher yields than sonicators. Processing at lower shear rates make it possible to rupture mammalian cells with high efficiency for the harvest of Adeno-Associated Virus (AAVs) Vectors for gene therapy.

      No Contamination

      Microfluidic processors offer media-free, negligible-wear processing that eliminates contamination of your sample.

      Flexibility

      Microfluidics offers a full range of processors capable of handling a wide range of cell types by optimizing pressure and cooling.
