Simultaneous immunoassay of multiple antigens and assay for cocaine metabolites

摘要

This invention includes an antigenic conjugate of ecgonine and a carrier which elicits anti-benzoylecgonine (cocaine metabolite) serum useful for the detection of cocaine metabolites in human organs and body fluids by immunoassay. The invention also includes the method of producing the anti-benzoylecgonine serum, the immunoassay method and composition including the anti-benzoylecgonine serum and a labeled benzoylecgonine and a non-labeled benzoylecgonine. The invention also includes a composition comprising a plurality of antigenic conjugates which elicit a multivalent anti-serum capable of complexing a plurality of antigens in a multiple immunoassay detection method. The invention includes the method of producing the multivalent anti-serum and an immunoassay method employing the multivalent anti-serum. The invention further includes a composition comprising the multivalent anti-serum and a plurality of labeled antigens and non-labeled antigens.
