Several inhibitor combinations are available, as well as water soluble & DMSO options.
Cell lysates contain endogenous proteases which degrade proteins and can affect sensitivity and reliability in protein expression research. It is therefore common practice to add protease inhibitors to lysate samples to protect proteins of interest. Our protease inhibitor cocktails inhibit a number of proteases including serine, cysteine and aspartic proteases.
Approximately 30% of known proteins can be reversibly phosphorylated in order to control a number of cellular processes. Protein kinases predominantly phosphorylate at serine, threonine and tyrosine residues - phosphatases reverse this phosphorylation. When studying these processes and pathways it is therefore essential to preserve the phosphorylation state of these proteins in your samples. Our phosphatase inhibitor cocktails inhibit a number of phosphatases including specific serine/threonine and tyrosine phosphatases as well as non-specific acid and alkaline phosphatases.
Combined protease and phosphatase inhibitor cocktail. Ideal for the ultimate protection of your protein samples. Available with and without EDTA, a metalloproteinase inhibitor.
