Enzyme to be trusted
Application Area:Protease for proteomics applications
"The sequencing grade modified trypsin comes in handy glass vials with 5 x 20 micrograms, either lyophilized or frozen. Excellent activity and high batch-to-batch reproducibility. Great both for complex protein mixtures and for individual proteins."

Nice and reliable product
"It is a nice protease which is resistant to auto-proteolysis and gives digestion to your protein."
Trypsin is a serine protease that specifically cleaves at the carboxylic side of lysine and arginine residues.
The stringent specificity of trypsin is essential for protein identification. Native trypsin is subject to autolysis, generating pseudotrypsin, which exhibits a broadened specificity including a chymotrypsin-like activity. Such autolysis products, present in a trypsin preparation, would result in additional peptide fragments that could interfere with database analysis of the mass of fragments detected by mass spectrometry.
Sequencing Grade Trypsin has been manufactured to provide maximum specificity. Lysine residues in the porcine trypsin have been modified by reductive methylation, yielding a highly active and stable molecule that is extremely resistant to autolytic digestion.
