Clone Host Grade Applications
Monoclonal Mouse Affinity Purified E B IP N
Carboxypeptidase A2 (CPA2) cleaves C-terminal residues with aromatic side chains
including Trp, Tyr and Phe. The 411 aa rhCPA2 consists of a pro region (aa 17 to 112) and
a mature chain (aa 113 to 417).
Catalog #C1204-07
ApplicationsSuitable for use in Western blot, Neutralization, Direct ELISA and Immunoprecipitation. Other applications have not been tested.
Recommended Dilutions:
Western blot:1-2ug/ml the detection limit is~10 ng/lane under non-reducing and reducing conditions. will increase sensitivity by 5 to 50 fold.
Neutralization: preincubate with the activated enzyme at different molar ratios at room temperature for 30 min. Then assay with N-acetyl-Phe-Thiaphe-OH. 50% of the enzymatic activity was inhibited at~ 1.5 ug/ml (IC50) under conditions in which the enzyme was
present at 0.1 ug/ml and the substrate concentration was 0.1 mM. Considering the
molecular masses of the enzyme (42kD) and the antibody (150kD), IC50 was achieved at
approximately 5:1 molar ratio of the antibody to the enzyme.
Immunoprecipitation: 25 ug/ml
Direct ELISA: 0.5-1.0 ug/mL
Optimal dilutions to be determined bythe researcher.
Storage and Stability
Lyophilized powder may be stored at -20°C. Reconstitute to nominal volume by adding sterile PBS. Aliquot and store at -20°C. Reconstituted product is stable for 12 months at -20°C.
