Abstract
Novel chemical analogs are disclosed for the essential heroin metabolite 6-O-acetyl morphine (6MAM). The analogs optionally can be made to contain protein reactive groups, and can be used to form protein conjugates, fluorescently labeled compounds, and solid-phase adsorbants. The proteins conjugates can be used in turn to raise antibodies reactive with 6MAM and having a low cross-reactivity with the closely related opiates, morphine and codeine. The antibodies can be used in combination with labeled analogs in exquisitely sensitive immunoassays suitable for testing for heroin abuse.
