Introduction Human Trypsin 1, encoded by the PRSS1 gene, is also known as cationic trypsinogen. It contains a signal peptide (residues 1‑15), a pro region (residues 16‑23), and a mature chain (residues 24‑247). Trypsin is part of the serine protease family. Trypsin cleaves lysine and arginine at the C-terminal side of the peptide. Trypsin optimum pH is pH-7 to 9. The enzyme is inhibited by serine protease inhibitors, e.g. PMSF, and by metal chelating agents, e.g. EDTA.

Product Description Recombinant Human Trypsin-1 is a genetically engineered protein expressed in E. coli and purified by standard chromatography techniques. Recombinant Human Trypsin-1 is free from any animal and human sources. There are no contaminating enzyme activities such as carboxypeptidase A and chymotrypsin. No protease inhibitors such as PMSF are contained in the preparation.
