When cells/tissues are undergoing lysis in the extraction process, the proteins in the sample become prone to degradation as a result of active endogenous proteases, yielding low yield and purity. In order to prevent this process of protein degradation, individual protease inhibitors or a mixture of protease inhibitors can be used to help preserve cellular protein by inhibiting the endogenous proteases present in the sample.

Cepham Life Sciences offers individual protease inhibitors, general and species-specific protease inhibitor cocktails that can be used for inhibiting active proteases, thereby preventing the protein degradation of precious research samples.
