Carboxypeptidase A2 Matched ELISA Antibody Pair Set,Human
Solid Phase Sandwich ELISA
Quantitative determination of Human Carboxypeptidase A2
1. Capture Antibody 1.0 mg/mL of mouse anti-CPA2 monoclonal antibody, Dilute to a working concentration of 2 μg/mL in CBS before coating. (Catalog: # 10499-MM02)
2. Detection Antibody 0.5 mg/mL rabbit anti-CPA2 monoclonal antibody conjugated to horseradish-peroxidase (HRP). Dilute to working concentration of 0.25 μg/mL in detection antibody dilution buffer before use. (Catalog: # 10499-R009)
3. Standard Each vial contains 50 ng of recombinant CPA2. Reconstitute with 1 mL detection antibody dilution buffer. After reconstitution, store at -20℃ to -80℃ in a manual defrost freezer. A seven-point standard curve usi ng 2-fold serial dilutions in sample dilution buffer, and a high standard of 800 pg/mL is recommended.

Carboxypeptidase A2 ( CPA2 ) is a secreted pancreatic procarboxy -peptidase, and cleaves the C-terminal amide or ester bond of peptides that have a free C-terminal carboxyl group. The hydrolytic action of CPA2 was identified with a preference towards long substrates with aromatic amino acids in their C-terminal end, particularly tryptophan. CPA2 comprises a signal peptide, a pro region and a mature chain, and can be activated after cleavage of the pro peptide. Three different forms of human pancreatic procarboxypeptidase A have been isolated, and the A1 and A2 forms are always secreted as monomeric proteins with different biochemical properties.
