  • Patent number: 7649085
    Abstract: Activated haptens useful for generating immunogens to HIV protease inhibitors, immunogens useful for producing antibodies to HIV protease inhibitors, and antibodies and labeled conjugates useful in immunoassays for the HIV protease inhibitor saquinavir. The novel haptens feature an activated functionality at the central, non-terminal hydroxyl group. Also described are monoclonal antibodies specific for saquinavir having less than 10% cross-reactivity with lopinavir, nelfinavir, amprenavir, ritonavir, and indinavir, and a murine hybridoma producing said antibodies.
    Type: Grant
    Filed: May 26, 2006
    Date of Patent: January 19, 2010
    Assignee: Roche Diagnostics Operations, Inc.
    Inventors: Gerald F. Sigler, Raymond A. Hui, Ina Deras, Richard Terry Root, Erasmus Huber, Herbert W. Von Der Eltz
  • Patent number: 7569676
    Abstract: The present invention comprises novel analogs of ecstasy-class compounds and novel ecstasy-class immunogens leashed out of, i.e., derived from, the methylenedioxy position. The invention also comprises unique monoclonal antibodies generated using MDO-leashed MDMA immunogens as well as unique conjugates and tracers. These antibodies, conjugates, and tracers are useful in immunoassays for the detection of ecstasy-class compounds in biological fluids.

  • Patent number: 7465797
    Abstract: Analogs of 6-monoacetyl morphine (6-MAM) are described. These include analogs derivatized at either the C-3 position, the C-6 position, or the nor position of the molecule. These analogs allow for elaboration with linkers terminated by a functional group such as an activated ester, the functional groups being useful for attaching the molecule to other entities such as proteins, polysaccharides, and reporter groups.

  • Patent number: 7193065
    Abstract: Activated haptens useful for generating immunogens to HIV protease inhibitors, immunogens useful for producing antibodies to HIV protease inhibitors, and antibodies and labeled conjugates useful in immunoassays for HIV protease inhibitors. The novel haptens feature an activated functionality at the central, non-terminal hydroxyl group common to all HIV protease inhibitors, e.g., saquinavir, nelfinavir, indinavir, amprenavir, ritonavir, lopinavir, and atazanavir.

  • Patent number: 7101980
    Abstract: Compounds including haptens, intermediates, and immunogens that are useful in the production of antibodies specific for the methylenedioxy class of amphetamine derivatives are described. Antibodies specific for the methylenedioxy class of amphetamine derivatives, reagent kits containing antibodies specific for the methylenedioxy class of amphetamine derivatives, methods of producing antibodies specific for the methylenedioxy class of amphetamine derivatives, and methods of detecting analytes including members of the methylenedioxy class of amphetamine derivatives are also described.
