Carboxypeptidase catalyzes the hydrolysis of the basic amino acids lysine, arginine and ornithine from the C-terminal position in polypeptides. It occurs as a zymogen in the pancreas in most vertebrates. This reagent is suited to enable an immunological appraoch to the study of protein and peptide structure.

FAQs for Carboxypeptidase B1/CPB1 Antibody (NBP2-89533AF647). (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 .
