Catalog# C455 Source HEK293 Description Recombinant Human Carboxypeptidase B/CPB1 is produced with our mammalian expression system in human cells. The target protein is expressed with sequence (His16-Tyr417) of Human CPB1 fused with a polyhistidine tag at the C-terminus. Names Carboxypeptidase B, Pancreas-Specific Protein, PASP, CPB1, CPB, PCPB Accession # P15086 Formulation Supplied as a 0.2 μm filtered solution of 20mM MES, 150mM NaCl, pH 5.5 Shipping The product is shipped on dry ice/ice packs. Storage Store at < -20°C, stable for 6 months after receipt.
Please minimize freeze-thaw cycles.Purity Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE. Endotoxin Less than 0.1 ng/μg (1 IEU/μg).

Expressed mainly in pancreas, CPB1 is a useful serum marker for acute pancreatitis and pancreatic graft rejection.Human CPB1 consists of a signal peptide, a pro region, and a mature chain. The purified rhCPB1 corresponds to the pro form, which can be activated by trypsin, the only pancreatic protease capable of generating active enzyme from the zymogen in vitro.
