Trypsin is a serine endopeptidase that specifically recognizes lysine and arginine residues, and cleaves peptide bonds at the carboxyl side of lysine and arginine residues.

Recombinant Trypsin from Yinjia Bio is a recombinant porcine trypsin expressed in Pichia pastoris. It is manufactured in compliance with GMP guidelines, and the entire production process is free of any animal-derived components, fundamentally eliminating the risk of contamination by animal-derived viruses such as swine influenza virus and porcine parvovirus. In addition, this product is naturally devoid of chymotrypsin activity and has been sterile-filtered.

Enzyme activity is strictly controlled in accordance with the internationally recognized USP activity standard, and the quality is comparable to international counterparts. The content of β-Trypsin in this product is above 80%, far exceeding the 70% standard specified in the Chinese Pharmacopoeia 2020 Edition. For storage stability, rigorous experiments have verified that the enzyme can be stably stored for a long time at 4 °C. Furthermore, its low missed cleavage rate in protein digestion experiments makes it a reliable and high-quality choice.
