Anti-Benzoylecgonine (BE) Antibody

Benzoylecgonine (BE) is the principal urinary metabolite of cocaine and serves as the primary biomarker used in clinical, workplace, and forensic toxicology screening for cocaine use. This mouse monoclonal IgG-1 reagent from Antibodies.com was raised against BE and is supplied as 1 mg of Protein A-purified antibody in a single vial, suitable as a capture or detection reagent in immunoassay development for the drug-of-abuse testing market.

The unconjugated format allows end users to conjugate the antibody themselves with HRP, biotin, or fluorescent labels according to their preferred assay architecture. Recommended use is in competitive immunoassay formats such as ELISA, where BE in the test sample competes with a coated BE-protein conjugate for antibody binding sites.

For handling, the lyophilized powder should be stored refrigerated and protected from light; for extended storage, aliquot and freeze at -20 °C, limiting repeated freeze-thaw cycles to preserve binding affinity. The product is supplied for research use only.
