  • Patent number: 9777069
    Abstract: Methods and reagents are disclosed for conducting assays for EDDP. The reagents include a moiety selected from the group consisting of poly(amino acid) label moieties, non-poly(amino acid) label moieties, poly(amino acid) immunogenic carriers, non-poly(amino acid) immunogenic carriers, non-label poly(amino acid) moieties, and non-immunogenic carrier poly(amino acid) moieties linked to 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine at the 3-position of one of the phenyl rings. Antibodies produced from immunogenic EDDP conjugates and labeled EDDP conjugates are employed in assays for determining the presence and/or amount of EDDP in samples suspected of containing EDDP.

  • Publication number: 20060116451
    Abstract: A composition includes at least one antioxidant moiety and at least one UV-absorbing moiety. The antioxidant moiety and the UV-absorbing moiety are maintained in proximity to each other. The UV-absorbing moiety and the antioxidant moiety can, for example, be attached to a common entity. The antioxidant moiety and the UV-absorbing moiety can, for example, be covalently attached within a single molecule. The UV-absorbing moiety can be attached sufficiently closely to the antioxidant moiety to enhance the stability of the antioxidant in an environment in which photooxidation can occur. In one embodiment, the UV-absorbing moiety is attached to the molecule to be juxtapositioned to the antioxidant moiety.
