Mouse myeloma cell line NS0-derived recombinant human Carboxypeptidase B1/CPB1
His16-Tyr417
Accession # P15086

Specificity

Detects human Carboxypeptidase B1/CPB1 in direct ELISAs and Western blots. In direct ELISAs and Western blots, approximately 10% cross‑reactivity with recombinant mouse (rm) CPB1 is observed and less than 5% cross-reactivity with recombinant human (rh) CPA1, rhCPA2, and rmCPA4 is observed.

Background: Carboxypeptidase B1/CPB1

Carboxypeptidase B1, encoded by the CPB1 gene, specifically cleaves the C-terminal Arg and Lys residues with a preference for Arg (1). Expressed mainly in pancreas, CPB1 is a useful serum marker for acute pancreatitis (2). The deduced amino acid sequence of human CPB1 consists of a signal peptide (residues 1 to 15), a pro region (residue 16 to 110), and a mature chain (residues 111 to 417). 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 (1).
