Template-directed photoligation

摘要

Methods, apparatus and compositions are presented for ligating ligands together which bind to a common receptor. 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 group 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.
