Photoactive probes and probe systems for detecting biological interactions are described. The photoactive probes include probes that combine both photocleavable and photoreactive moieties. The photoactive probe systems can include a first probe comprising a photocatalytic group and a second probe comprising a group that can act as a substrate for the reaction catalyzed by the photocatalytic group. The probes and probe systems can also include groups that can specifically bind to a binding partner on a biological entity of interest and a detectable group or a precursor thereof. The probes and probe systems can detect spatiotemporal interactions of proteins or cells. In some embodiments, the interactions can be detected in live cells. Also described are methods of detecting the biological interactions.
描述了用于检测生物相互作用的光活性探针和探针系统。光活性探针包括同时结合光解和光反应基团的探针。光活性探针系统可以包括第一探针,其中包括光催化基团,以及第二探针,其中包括可作为光催化基团催化反应底物的基团。探针和探针系统还可以包括能够特异性结合到感兴趣生物实体上的结合伙伴的基团,以及可检测的基团或其前体。这些探针和探针系统可以检测蛋白质或细胞的时空相互作用。在某些实施方式中,这些相互作用可以在活细胞中检测到。还描述了检测生物相互作用的方法。
