    • This invention relates to the production of polyclonal and monoclonal antibodies to specific sites of rapamycin (Sirolimus). The reactivity of these poly and monoclonal antibodies make them particularly useful for immunoassays for therapeutic drug monitoring (TDM). These immunoassays or TDM kits may include polyclonal or monoclonal antibodies to specific sites of rapamycin. These kits may also include various combinations of polyclonal antibodies, polyclonal and monoclonal antibodies or a panel of monoclonal antibodies. Rapamycin conjugate immunogens are prepared for the immunization of a host animal to produce antibodies directed against specific regions of the rapamycin molecule. By determining the specific binding region of particular antibody, immunoassays which are capable of distinguishing between the parent molecule, active metabolites, inactive metabolites and other structurally similar immunosuppressant compounds are developed. The use of divinyl sulfone (DVS) as the linker arm molecule for forming rapamycin-protein conjugate immunogens is described. DVS-linked rapamycin-protein conjugates were found to elicit antibodies with greater specificity to the rapamycin molecule than succinate linked conjugates.
    • 本发明涉及针对雷帕霉素(西罗莫司)特定部位的多克隆和单克隆抗体的产生。 这些多抗和单克隆抗体的反应性使其对治疗药物监测(TDM)的免疫测定特别有用。 这些免疫测定或TDM试剂盒可以包括针对雷帕霉素的特定位点的多克隆或单克隆抗体。 这些试剂盒还可以包括多克隆抗体,多克隆和单克隆抗体或一组单克隆抗体的各种组合。 制备雷帕霉素结合物免疫原用于免疫宿主动物以产生针对雷帕霉素分子的特定区域的抗体。 通过确定特定抗体的特异性结合区域,开发了能够区分亲本分子,活性代谢物,无活性代谢物和其他结构类似的免疫抑制剂化合物的免疫测定。 描述了使用二乙烯基砜(DVS)作为形成雷帕霉素 - 蛋白质结合物免疫原的连接臂分子。 发现DVS连接的雷帕霉素 - 蛋白质缀合物比琥珀酸酯连接的缀合物引起对雷帕霉素分子具有更高特异性的抗体。
