Description

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 and clostripain . 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.
