Benzoylecgonine (BE)-BSA Antigen

A synthetic hapten–carrier conjugate from Antibodies.com, this lyophilized preparation couples the cocaine metabolite benzoylecgonine to bovine serum albumin to generate a high-molecular-weight immunogen. The vial contains 1 mg of the BSA conjugate in a salt-free format, ready for reconstitution with distilled water or assay buffer to the working concentration required by each protocol. As an immunogen, it supports antibody production in host species; as a coating or calibration reagent, it fits competitive immunoassay formats targeting benzoylecgonine, including ELISA plate-coating, lateral flow test development, and quantitative calibrator preparation. Lyophilization provides extended shelf stability when the vial is stored refrigerated and protected from light, with long-term storage below freezing and freeze-thaw cycles avoided to preserve conjugate integrity. The reagent is supplied for research use only and is not intended for diagnostic or therapeutic applications.
