J67522 Trypsin, Certified Mass Spec Grade

Trypsin is a serine protease that specifically cleaves peptide bonds at the carboxyl side of arginine and lysine residues. This product is highly purified and suitable for proteomics applications. Trypsin can be used for peptide mapping and protein sequencing applications as it generates a reproducible cleavage pattern with a limited number of fragments. This formulation is TPCK-treated to inhibit chymotryptic acivity.
