Trypsin is a serine peptideptid endonuclease secreted by the pancreas，with recognition sites of lysine and arginine，and cleavage sites of carboxyl terminus in lysine and arginine residues. This product is recombinant porcine trypsin expressed by Pichia pastoris，produced under GMP regulations，does not contain any animal-derived ingredients，and has no animal-derived virus contamination (such as swine flu virus，porcine parvovirus，etc.). It is naturally lacking in chymotrypsin activity and has been filtered and sterilized. The activity of this product is subject to the international general activity (USP)，which is better than that of similar imported products，among which the HPLC content of β-Trypsin can reach more than 80%，which is higher than the 2020 version of the Chinese Pharmacopoeia standard (>70%)，the storage stability is very high (94% activity can still be maintained after 20 months of storage at 4°C)，and the leakage rate of proteomic enzymatic hydrolysis is lower than that of imported products.

Protein analysis, such as protein mass spectrometry, sequencing, and peptide mapping analysis

High purity: β-Trypsin proportion > 80%; The proportion of α-Trypsin is less than 20%. Protein purity: > 95%

High quality: It can rival imported brands in aspects such as protein or peptide identification, omission rate, peptide graph analysis, and common PTM analysis.

Super stability: It can still maintain high enzyme activity after being stored at 4℃ for 24 months or at 37℃ for one week. It contains no animal-derived ingredients and no other protease activities. ; It contains no protease inhibitors, such as PMSF, etc.
