Other Notes
An alkylating reagent that may react with histidine or cysteine residues at the active site of enzymes. Inactivates serine proteases such as trypsin 1,2,3 and clostripain 4. Chymotrypsin is not affected. To prevent proteolytic degradation, a combination of TLCK and TPCK can be used throughout the isolation of proteins, as in the isolation of histones.5
