ProteoSure™ Recombinant Carboxypeptidase B, 100 mg, 14-RCPB-100MG, Marvelgent biosciences (CAT#: STEM-GT-3039-LGZ)

Carboxypeptidase B catalyzes the hydrolysis of lysine, arginine, and histidine at the C-terminus of polypeptides. Its molecular weight is 33.8 kDa, the optimum pH is 8.0, and the pI is 6.0. Carboxypeptidase B is competitively inhibited by arginine and lysine. This enzyme is also inhibited by metal chelators such as EDTA.

Marvelgent's recombinant carboxypeptidase B was expressed in E. coli and purified by high pressure liquid chromatography. There is no trace contamination of proteases, such as carboxypeptidase A or chymotrypsin, and no protease inhibitors, such as PMSF.

100% Free of Animal Origin
By using Marvelgent's recombinant carboxypeptidase B, it helps avoid contamination by viruses and any other potential adventitious agents, which can be found in animal-derived carboxypeptidase B.

High purity
Recombinant carboxypeptidase B exhibits highly specific enzymatic activity without contaminating proteases, such as chymotrypsin or carboxypeptidase A, commonly found in enzymes of animal origin.

Stablize
Sterile freeze-dried powder is provided with high stability in transportation and storage.
