Powerful proteases can begin degrading your protein samples from the moment cells or tissues are lysed. Protein yield and sample quality can be drastically reduced by proteases. Complex protein solutions are usually treated with a mixture of serveral protease inhibitors in order to preserve the native state of proteins.
