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.

Saquinavir conjugates and antibodies useful in immunoassay

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.

Protease inhibitor conjugates and antibodies useful in immunoassay

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.

6-monoacetylmorphine derivatives useful in immunoassay

The present invention relates to monoclonal antibodies that specifically bind buprenorphine and/or at least one metabolic product thereof. The present invention further relates to buprenorphine metabolite conjugates for the production of monoclonal antibodies that specifically bind buprenorphine and/or at least one metabolic product thereof and hybridoma cells that produce the monoclonal antibodies. The invention also relates to immunoassay methods for determining buprenorphine and/or one or more buprenorphine metabolites in a sample using the novel antibodies and conjugates of the present invention.

Monoclonal antibodies specific for buprenorphine and metabolites thereof

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.

Activated haptens useful for generating immunogens to the HIV protease inhibitor atazanavir, immunogens useful for producing antibodies to atazanavir, and antibodies and labeled conjugates useful in immunoassays for determination of atazanavir. The haptens feature an activated functionality at the central, non-terminal hydroxyl group.

Methods of inhibiting transmission of a costimulatory signal of lymphocytes

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.

Derivatives, conjugates, and antibodies for detecting ecstasy-class analytes

Analogs of saquinavir functionalized at the quinoline portion of the molecule are described. These include pyridyl analogs (replacing the quinoline ring) with a functional handle out of the ring allowing for elaboration with linkers terminated by a functional group such as an activated ester which are useful for attaching the molecule to other entities such as proteins, polysaccharides, and the like. Analogs of saquinavir derivatized out of the quinoline ring are also described.
