WebTrypsin-ultra™, Mass Spectrometry Grade is a serine endopeptidase. It selectively cleaves peptide bonds C-terminal to lysine and arginine residues (1). Trypsin-ultra is treated with L- (tosylamido-2-phenyl) ethyl chloromethyl ketone (TPCK) to inactivate any remaining chymotryptic activity. It is modified by acetylation of the ε-amino groups ... WebStringent specificity of trypsin activity is crucial for protein identification. However, specificity can be compromised by autolysis, which generates pseudotrypsin with a broadened specificity and chymotrypsin-like activity (Keil-Dlouha et al., 1971). Autolysis can result in additional peptide fragments that could interfere with database analysis and …
