Background

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 (aa) sequence of human CPB1 consists of a signal peptide (aa 1-15), a pro region (aa 16-110), and a mature chain (aa 111-417). Human CPB1 shares 98%, 84%, 76%, 75%, and 84% aa sequence identity with chimpanzee, dog, rat, mouse and chicken CPB1, respectively.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Primary Antibodies are guaranteed for 1 year from date of receipt.

FAQs for Carboxypeptidase B1/CPB1 Antibody (FAB2897N). (Showing 1 - 2 of 2 FAQ).

1. I use porcine carboxypeptidase B (CPB) in my fermentation process. I want to detect the residual CPB in my finished product preferably by ELISA/western blot. How will antibody pairs from Novus Biologics help me do that? Is a colorimetric assay possible with the antibody pair?
   • Any detection system can be employed when using the antibody pairs. The detection system will depend on the secondary used against the detection primary antibody from the pair, and the conjugate on the secondary antibody. The pair will work effectively in capturing the protein of interest, and subsequently detecting it with the second antibody in the pair for ELISA. This pair is not evaluated in Western Blot directly, but there Novus carries similar primary antibodies that we have that are validated in that application.
2. I am trying to establish ELISA detection for carboxy peptidase. I am using a rat recombinant carboxypeptodase b from Roche diagnostics (cat no.03358682103). Can you please suggest the suitable kit .
