Mouse Carboxypeptidase A1/CPA1 Antibody Summary

Species Reactivity
Mouse
Specificity
Detects mouse Carboxypeptidase A1/CPA1 in direct ELISAs and Western blots. In direct ELISAs, approximately 20% cross-reactivity with recombinant human (rh) CPA1 is observed and approximately 10% cross-reactivity with rhCPA2, rhCPB1, and recombinant mouse CPA4 is observed.
Source
Polyclonal Goat IgG
Purification
Antigen Affinity-purified
Immunogen
Mouse myeloma cell line NS0-derived recombinant mouse Carboxypeptidase A1/CPA1
Asn17-Tyr419
Accession # Q7TPZ8
Formulation
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.

Applications

Recommended Concentration
Sample
Western Blot
0.1 µg/mL
Recombinant Mouse Carboxypeptidase A1/CPA1 (Catalog # 2765-ZN)
Immunoprecipitation
25 µg/mL
Conditioned cell culture medium spiked with Recombinant Mouse Carboxypeptidase A1/CPA1 (Catalog # 2765-ZN), see our available Western blot detection antibodies
Neutralization
Measured by its ability to neutralize Recombinant Mouse Carboxypeptidase A1/CPA1 (0.25 µg/mL, Catalog # 2765‑ZN) cleavage of the fluorogenic peptide substrate Ac-Phe-Thiaphe-OH (100 µM). The Neutralization Dose (ND50) is typically 2 µg/mL.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Background: Carboxypeptidase A1/CPA1

Carboxypeptidase A1 encoded by the CPA1 gene cleaves the C-terminal amide or ester bond of peptides that have a free C-terminal carboxyl group (1). It prefers the C-terminal residues with aromatic or branched aliphatic side chains including Phe, Tyr, Trp, Leu or Ile. It is important in the degradation of food proteins to produce essential amino acids such as Phe and Trp. The deduced amino acid sequence of mouse CPA1 consists of a signal peptide (residues 1 to 16), a pro region (residue 17 to 110), and a mature chain (residues 111 to 419). The purified recombinant CPA1 corresponds to the pro form, which can be activated and assayed.
