Application
Alkylating reagent for cysteine residues in peptide sequencing. By virtue of reaction with cysteine, it is an irreversible inhibitor of enzymes with cysteine at the active site.1 It reacts much more slowly with histidine residues, but that activity is responsible for inhibition of ribonuclease.2
