Protease and phosphatase inhibitors (cocktails and individual inhibitors) are essential tools for researchers involved in proteomic studies including protein expression and characterization, biomarker discovery, mapping of post-translational modifications, protein expression profiling, and the quantitative measurement of proteins. Adding a protease inhibitor cocktail or protease inhibitor during preparative or purification steps helps ensure protein integrity for downstream analysis and sample characterization. For phosphorylated proteins, PhosphoSafe Extraction Reagent and phosphatase inhibitor cocktails help preserve their phosphorylation state in cell lysates and tissue extracts during extraction and purification steps. | |
