商品信息
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).


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.
