Methods are disclosed for determining minute quantities of an analyte in a medium suspected of containing the analyte. One method comprises treating a medium suspected of containing an analyte under conditions such that the analyte, if present, causes a substrate having an oxidant cleavable linker and a photosenstizer to come into close proximity. The photosenstizer generates singlet oxygen which oxidatively cleaves the linker to form a product which can be detected in a sandwich detection assay such as LOCI. The amount of product detected is related to the amount of analyte in the medium. Compositions, kits, and compounds are also disclosed.
本发明公开了一种用于确定疑似含有分析物的介质中微量分析物的方法。其中一种方法包括在条件下处理疑似含有分析物的介质,使得如果分析物存在,则会使得具有氧化剂可分解连接剂和光敏剂的底物进入接近状态。光敏剂产生单线态氧,氧化性地裂解连接剂形成可在夹心检测测定(如LOCI)中检测到的产物。检测到的产物量与介质中分析物的量有关。本发明还公开了组合物、试剂盒和化合物。
