The present invention is directed to novel tricyclic antidepressant drug derivatives synthesized for covalent attachment to proteins or polypeptide antigens for use in the preparation of antibodies or receptors to tricyclic antidepressant drugs and tricyclic antidepressant metabolites. The new derivatives are characterized by a saturated double bond on the amitriptyline portion of the molecule and are represented by the structure
where R1 is a saturated or unsaturated, substituted or unsubstituted, straight or branched chain of 0-10 carbon or heteroatoms, X is a linker group consisting of 0-2 substituted or unsubstituted aromatic rings, and Y is an activated ester or NH—Z, where Z is a poly(amino acid). The novel tricyclic antidepressant activated hapten derivatives are useful for preparing tracers and conjugates for tricyclic antidepressant immunoassays, including an enzyme immunoassay and a microparticle capture inhibition assay using an antibody produced from the novel immunogen with a conjugate derivatized either at the N-1 position of imipramine or at the C-2 position of dihydroamitriptyline.
