The present invention is directed to novel amphetamine derivatives which are synthesized for the covalent attachment to antigens (proteins or polypeptides) for the preparation of antibodies or receptors to amphetamine and amphetamine metabolites. The resulting novel antigens may be used for the production of antibodies or receptors using standard methods. Once generated, the antibodies or receptors and the novel derivatives which are covalently attached to proteins, polypeptides or labels may be used in the immunoassay process.
Water soluble hybrid phthalocyanine derivatives useful in competitive and noncompetitive assays immunoassays, nucleic acid and assays are disclosed and claimed having (1) at least one donor subunit with a desired excitation peak; and (2) at least one acceptor subunit with a desired emission peak, wherein said derivative(s) is/are capable of intramolecular energy transfer from said donor subunit to said acceptor subunit. Such derivatives also may contain an electron transfer subunit. Axial ligands may be covalently bound to the metals contained in the water soluble hybrid phthalocyanine derivatives. Ligands, ligand analogues, polypeptides, proteins and nucleic acids can be linked to the axial ligands of the dyes to form dye conjugates useful in immunoassays and nucleic acid assays.

The present invention is directed to novel PCP derivatives which are synthesized for the covalent attachment to antigens or receptors (proteins or polypeptides) for the preparation of antibodies or receptors to PCP and PCP analogue metabolites. The resulting novel antigens may be used for the production of antibodies or receptors using standard methods. Once generated, the antibodies and the novel derivatives which are covalently attached to proteins, polypeptides or labels may be used in the immunoassay process.
Compounds are provided for the preparation of reagents, including labels which can be used in immunoassays of cocaine and cocaine metabolites. The compounds are derivatives of cocaine which are conjugated to antigenic proteins or polypeptides for the formation of antibodies for use in immunoassays. The compounds also may be conjugated to labels for use in immunoassays.
