Depending on the source, the protein has to be brought into
solution by breaking the tissue or cells containing it.
There are several methods to achieve this: Repeated
freezing and thawing, sonication, homogenization by high
pressure, clarification via cellulose-based depth filters,
or permeabilization by organic solvents. The method of
choice depends on how fragile the protein is and how sturdy
the cells are. After this extraction process soluble
proteins will be in the solvent, and can be separated from
cell membranes, DNA etc. by centrifugation. The extraction
process also extracts proteases, which will start digesting
the proteins in the solution. If the protein is sensitive
to proteolysis, it is usually desirable to proceed quickly,
and keep the extract cooled, to slow down proteolysis
