Q & A

What is the purpose of cell disruption in biological processes?

Cell disruption is used to break cells in order to recover intracellular contents, such as proteins or viruses, while maintaining the integrity of these materials. This process is key for gene therapy, diagnostic testing, pharmaceutical development, and vaccine production.

Why is cell lysis important for recovering intracellular contents?

Cell lysis is essential because without it, particles of interest such as enzymes, nucleic acids, vaccine antigens, and viral vectors cannot be accessed if they are not secreted extracellularly. Lysis allows for the efficient recovery of these materials.

What challenges arise when attempting to maintain the integrity of intracellular contents during cell disruption?

Challenges include minimizing damage to intracellular materials caused by temperature increases or excessive force during the disruption process. Additionally, clarifying and purifying these contents from cell debris presents downstream sterile filtration challenges.

How does microfluidics technology assist in the cell disruption process?

Microfluidics technology, specifically through microfluidizer processors, applies a constant, controlled shear rate to break cell walls and membranes while preserving the integrity of intracellular contents. An integrated cooling system also ensures proteins stay intact during high-pressure processing.

What makes microfluidizer processors superior to other cell disruption methods?

Microfluidizer processors are superior due to their ability to maintain consistent controlled shear rates, efficient cooling, contamination-free processing, and scalability from lab to production. These factors ensure higher protein recovery, less waste, and reduced damage to sensitive materials.

What advantages do microfluidizer processors offer in terms of scalability?

Microfluidizer processors can scale up from lab-scale to production-scale while maintaining consistent results. Each batch is processed the same way, which ensures reproducibility and efficiency across different cell types and volumes.

How does microfluidizer technology ensure consistent results during cell rupture?

Microfluidizer technology uses a controlled shear rate combined with a revolutionary interaction chamber to ensure that all cells receive the same pressure and shear rate. This results in fewer passes needed to process material, saving time and ensuring consistent results.

What types of cells can be processed using microfluidizer processors?

Microfluidizer processors are versatile and can process various cell types, including bacterial cells like E. coli, yeast cells, mammalian cells, and algae cells.

What role does temperature control play in microfluidizer processing?

Temperature control is crucial in microfluidizer processing to prevent damage to temperature-sensitive intracellular contents. The integrated cooling system ensures that proteins and other materials stay intact during high-pressure processing.

How does microfluidizer processing minimize downstream challenges like filtration and separation?

Microfluidizer processing results in cell contents that are easier to centrifuge, separate, and filter, with minimal clogging. This simplifies downstream processes and reduces the need for additional purification steps required by other methods.
