ProteoSure™ Recombinant Human Trypsin, 1 gram, 14-RHT-1G, Marvelgent biosciences (CAT#: STEM-GT-3033-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 optimal pH value of trypsin is between 7.8 and 8.7. The enzyme is inhibited by serine protease inhibitors such as PMSF and metal chelators such as EDTA.

Recombinant human trypsin is a genetically engineered protein expressed in Escherichia coli and purified by high pressure liquid chromatography. The amino acid sequence is identical to that of human trypsin 2. No contaminating enzyme activity from carboxypeptidase A or chymotrypsin. No protease inhibitors such as PMSF are used in the production process.

Animal source free
The use of recombinant human trypsin eliminates the potential risk of contamination with viruses and any other potential variable factors found in trypsin of animal origin. Recombinant Human Trypsin is 100% AOF and produced in an ISO9001 certified facility.

Human recombination
This product is recombinant human trypsin. The amino acid sequence is identical to that of human trypsin 2. Suitable for applications requiring low immunogenicity components.

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

Highly pure
Recombinant human trypsin has superior specificity and purity.
No other contaminating proteases such as chymotrypsin or carboxypeptidase A.
HPLC method purity greater than 95%.
