ProteoSure™ Recombinant Porcine Trypsin, 5 x 100 mg, 14-RPT-500MG, Marvelgent biosciences (CAT#: STEM-GT-3028-LGZ)

Trypsin is a member of the serine protease family. Trypsin cleaves the polypeptide at the C-terminus of the lysine and arginine amino acid residues. The optimum pH for trypsin is between 7-9. The enzyme is inhibited by serine protease inhibitors such as PMSF and metal chelators such as EDTA.

Recombinant porcine trypsin is a genetically engineered protein expressed in Escherichia coli and purified by high pressure liquid chromatography. No contaminating enzyme activity from carboxypeptidase A or chymotrypsin. No protease inhibitors such as PMSF are used in the production process.

No animal origin
The use of recombinant porcine trypsin eliminates the potential risk of viral contamination and any other potential variables found in trypsin of animal origin. Recombinant Porcine Trypsin is 100% animal source free and manufactured in an ISO9001 facility.

Stable
Recombinant porcine trypsin is supplied as a sterile lyophilized powder. It minimizes the risk of contamination and loss of activity during transport and storage.

High purity
Recombinant porcine trypsin has high purity and specificity.
No other contaminating proteases such as chymotrypsin or carboxypeptidase A.
