    • Methods are disclosed for designing an antibody reagent for use in an assay for the detection of an analyte to obtain an optimum assay sensitivity and/or dynamic range. The antibody reagent is a conjugate of a small molecule attached by a spacer group to an antibody for the analyte. The method comprises controlling, in the preparation of the conjugate, reaction parameters comprising the hydrophobicity or hydrophilicity of the spacer group, the length of the spacer group, the number of molecules of the small molecule attached to the antibody and the point of attachment of the small molecule to the antibody to obtain an optimum assay sensitivity and/or dynamic range. In some embodiments the method comprises preparing two or more conjugates by selecting a set of parameters for each conjugate wherein the set of parameters is different for each conjugate, conducting an assay for the analyte employing each conjugate and selecting for use in the assay the conjugate that provides the optimum assay sensitivity and/or dynamic range.

    • This invention relates to agents and conjugates that can be used to detect and isolate target components from complex mixtures such as proteins and protein fragments from biological samples from in vivo and in vitro sources. Agents comprise a detectable group bound to a photoreactive group. Conjugates comprise agents coupled to substrates by covalent bounds which can be selectively cleaved with the administration of electromagnetic radiation. Targets substances labeled with detectable molecules can be easily identified and separated from a heterologous mixture of substances. Exposure of the conjugate to radiation releases the target in a functional form and completely unaltered. Using photocleavable molecular precursors as the conjugates, label can be incorporated into macromolecules, the nascent macromolecules isolated and the label completely removed. The invention also relates to targets isolated with these conjugates which may be useful as pharmaceutical agents or compositions that can be administered to humans and other mammals.
    • 本发明涉及可用于从体内和体外来源的生物样品的复杂混合物如蛋白质和蛋白质片段检测和分离靶组分的试剂和缀合物。 试剂包含与光反应性基团结合的可检测基团。 缀合物包括通过共价界限偶联到底物的试剂,其可以通过施用电磁辐射被选择性地切割。 目标可以用可检测分子标记的物质可以很容易地识别,并与物质的异源混合物分离。 缀合物暴露于放射线以功能形式释放靶,完全不变。 使用可光致发光的分子前体作为共轭物,标记可以并入大分子中,分离出新生大分子,并将标记完全除去。 本发明还涉及用这些缀合物分离的靶,其可用作可以施用于人和其它哺乳动物的药剂或组合物。

    • This invention relates to agents and conjugates that can be used to detect and isolate target components from complex mixtures such as nucleic acids from biological samples, cells from bodily fluids, and nascent proteins from translation reactions. Agents comprise a detectable moiety bound to a photoreactive moiety. Conjugates comprise agents coupled to substrates by covalent bounds which can be selectively cleaved with the administration of electromagnetic radiation. Targets substances labeled with detectable molecules can be easily identified and separated from a heterologous mixture of substances. Exposure of the conjugate to radiation releases the target in a functional form and completely unaltered. Using photocleavable molecular precursors as the conjugates, label can be incorporated into macromolecules, the nascent macromolecules isolated and the label completely removed. The invention also relates to targets isolated with these conjugates which may be useful as pharmaceutical agents or compositions that can be administered to humans and other mammals. Useful compositions include biological agents such as nucleic acids, proteins, lipids and cytokines. Conjugates can also be used to monitor the pathway and half-life of pharmaceutical composition in vivo and for diagnostic, therapeutic and prophylactic purposes. The invention also relates to kits comprised of agents and conjugates that can be used for the detection of diseases, disorders and nearly any individual substance in a complex background of substances.
