Cell Disruption - an overview | ScienceDirect Topics

Intracellular products such as recombinant insulin, which are typically produced in microbial host cells, demand a product release step to remove them from the cell. How this is performed determines the quantity of released contaminants, the particle size distribution of cell debris and the physical properties of the resultant process stream, which all impact on the performance of the ...

Disruption of microbial cells for intracellular products

A common laboratory-scale mechanical method for cell disruption uses glass, ceramic or steel beads, 0.1 to 2 mm in diameter, mixed with a sample suspended in aqueous media. First developed by Tim Hopkins in the late 1970s, the sample and bead mix is subjected to high level agitation by …
