Benzoylecgonine (BE)-HRP Antigen

Cocaine metabolite detection in forensic toxicology and drug screening workflows relies on carefully characterized benzoylecgonine conjugates. This Benzoylecgonine-HRP Antigen is supplied as a ready-to-use liquid reagent prepared by covalent coupling of the benzoylecgonine hapten to horseradish peroxidase (HRP) for direct enzymatic signal generation. The conjugate functions as a labeled antigen in competitive immunoassay development, supporting quantification of the major cocaine metabolite in urine, oral fluid, or matched sample types collected during workplace screening, clinical diagnostics, and rehabilitation monitoring programs. Each vial is supplied as a 1 mL liquid format, simplifying dilution into assay buffer and reducing preparation steps before plate coating or competitive binding reactions. Antibody pairs and calibration standards are sourced separately to support complete competitive assay setup at the researcher's bench. Researchers building lateral flow tests or other immunoassay formats benefit from the HRP label, which permits chromogenic or chemiluminescent readout depending on substrate choice, while the small-molecule conjugate format integrates readily into existing antibody validation pipelines. Antibodies.com provides this reagent under its antigens product line for research and forensic use only.
