WebApr 11, 2024 · Materials & methods: The performance of commercially available next-generation trypsins was assessed based on the digestion of protein standards in buffer and complex matrix by LC–high-resolution MS. Results: The performance of all next-generation trypsins assessed exceeded that of an overnight tryptic digest in a fraction of the time. WebTrypsin is a serine protease that specifically cleaves at the carboxylic side of lysine and arginine residues. The distribution of Lys and Arg residues in proteins is such that trypsin digestion yields peptides of molecular weights that can be analyzed by mass spectrometry. The pattern of peptides obtained is used to identify the protein.
