Human Carboxypeptidase A2/CPA2 Antibody Summary

Species Reactivity

Human

Specificity

Detects human Carboxypeptidase A2/CPA2 in direct ELISAs and Western blots. In Western blots, recognizes the pro form but not the activated enzyme.

Source

Monoclonal Mouse IgG_2B Clone # 384014

Purification

Protein A or G purified from hybridoma culture supernatant

Immunogen

Mouse myeloma cell line NS0-derived recombinant human Carboxypeptidase A2/CPA2
Tyr17-His417
Accession # P48052

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.

Applications

Recommended Concentration

Sample

Western Blot

1 µg/mL

Recombinant Human Carboxypeptidase A2 (Catalog # 2896-ZN)

Immunoprecipitation

25 µg/mL

Conditioned cell culture medium spiked with Recombinant Human Carboxypeptidase A2/
CPA2 (Catalog # 2896-ZN), see our available Western blot detection antibodies

Neutralization

Measured by its ability to neutralize Recombinant Human Carboxypeptidase A2/CPA2 (0.1 µg/mL, Catalog # 2896‑ZN) cleavage of the fluorogenic peptide substrate N-acetyl-Phe-Thiaphe-OH (0.1 mM). The Neutralization Dose (ND₅₀) is typically 1.5 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 A2/CPA2

Carboxypeptidase A2 encoded by the CPA2 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 side chains including Phe, Tyr, and Trp. The deduced amino acid sequence of human CPA2 consists of a signal peptide (residues 1 to 16), a pro region (residues 17 to 112), and a mature chain (residues 113 to 417).
