Methods, apparatus and compositions are presented for ligating ligands together which bind to a common target. One embodiment includes polynucleotide probes having photoreactive functional groups. The probes are capable of assuming substantially contiguous reactive positions on a target polynucleotide placing the photoreactive groups in juxtaposition. Activation of the photoreactive functional groups with radiant energy form a probe reaction product in which the probes are bound to each other.
本文介绍了将与共同目标结合的
配体连接在一起的方法、装置和组合物。其中一个实施方案包括具有光活性官能团的多核苷酸探针。这些探针能够在目标多核苷酸上占据基本连续的反应位置,并将光活性基团并置。光活性官能团在辐射能的激活下形成探针反应产物,其中的探针相互结合。
