  • Patent number: 7067270
    Abstract: An object of the present invention is to provide a method for detecting a protein using a nonradioactive label which is prevented to a smaller extent than in the case of the interaction of biotin/(strepto)avidin, and which achieves higher detection sensitivity than that of the detection system using DIG. The present invention provides a method for detecting a target substance, which comprises steps of: (A) allowing a target substance to come into contact with a protein labeled with a compound having a 6-membered ring, so as to carry out a binding reaction; and (B) detecting the protein labeled with the compound having a 6-membered ring, which was bound to the target substance, by using an antibody against the above compound having a 6-membered ring.

  • Patent number: 7038021
    Abstract: The object of present invention is to provide an immunoassay for dioxins which can rapidly and simply afford measured values having a good correlation with analytical values of dioxins by the official method (GC/MS method). The above object is achieved by using the monoclonal antibody of the present invention having not only a reactivity with the indicator isomer among 17 kinds of PCDDs and PCDFs each having a predetermined WHO-TEF value, but also a high cross-reactivity with several kinds of dioxin isomers having five or six chlorine atoms which contribute largely to a TEQ value, and also having a stable reactivity with the antigens in a measuring solvent.

  • Patent number: 6991911
    Abstract: Methods, compositions and kits are disclosed. The methods are directed to determining the presence of entactogen analytes such as, for example, 3,4-methylenedioxyamphetamine (MDA), 3,4-methylenedioxy-methamphetamine (MDMA), 3,4-methylenedioxy-ethylamphetamine (MDEA) and 4-hydroxy-3-methoxy-methamphetamine (HMMA). The method comprises providing in combination in a medium (i) a sample suspected of containing the compound and (ii) an antibody raised against a compound of Formula I that comprises a protein. The medium is examined for the presence a complex comprising the compound and the antibody where the presence of such as complex indicates the presence of the compound in the sample. In one aspect of the above embodiment, the combination further comprises a label conjugate of the compound Formula I.

  • Patent number: 6992177
    Abstract: 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.
