ProteoSure™ Recombinant Carboxypeptidase B
Recombinant Carboxypeptidase B is 100% Animal Origin Free, >95% pure, suited for bioprocessing and bioproduction, manufactured in ISO9001 facility. ... Read more
Carboxypeptidase B catalyzes the hydrolysis of basic amino acids lysine, arginine, and histidine at the C-terminal end of polypeptides. The molecular weight is 33.8 kDa, the optimum pH is 8.0, and pI is 6.0. Carboxypeptidase B is competitively inhibited by arginine and lysine. The enzyme is also inhibited by metal chelating agents, e.g., EDTA.
Marvelgent's recombinant Carboxypeptidase B is expressed in E.coli and is purified by high pressure liquid chromatography. No trace contamination with proteases, such as carboxypeptidase A or chymotrypsin, nor protease inhibitors such as PMSF.
- 100% Animal Origin Free (AOF)
By using of Marvelgent’s recombinant carboxypeptidases B, it helps to avoid contamination with viruses and any other potential adventitious agents that can be found in animal-derived carboxypeptidase B.
- High purity
Recombinant carboxypeptidase B exhibits highly specific enzymatic activity with no contaminating proteases , such as chymotrypsin or carboxypeptidase A that are commonly found in animal-originated enzymes.
Provided as sterile lyophilized powder, highly stable during transportation and storage.
