PHOTOCHEMICAL METHOD OF LABELLING NUCLEIC ACIDS

摘要

In a test for the presence of a particular nucleic acid in a test sample wherein the same is subjected to hybridizing conditions with a lbeled nucleic acid probe, and the product is assayed for the presence of said label, the improvement wherein said probe comprises a probe according to claim 1. A labeled nucleic acid probe comprising (a) a nucleic acid component, (b) a nucleic acid-binding ligand photochemically linked to the nucleic acid component, (c) a label and (d) a spacer chemically linking (b) and (c).
