Cell disruption is a method or process for releasing biological molecules from inside a cell.
The production of biologically-interesting molecules using cloning and culturing methods allows the study and manufacture of relevant molecules.Except for excreted molecules, cells producing molecules of interest must be disrupted. This page discusses various methods.
If only a few microliters of sample are available, care must be taken to minimize loss and to avoid cross-contamination.

Disruption of cells, when hundreds or even thousands of liters of material are being processed in a production environment, presents a different challenge.
