Fast photochemical method of labelling nucleic acids for detection purposes in hybridization assays

摘要

A labeled nucleic acid probe comprising (a) a nucleic acid component, (b) a nucleic acid-binding ligand photochemically linked to the nucleic acid component, and (c) a label chemically linked to the nucleic acid-binding ligand. The label can be a specifically bindable ligand such as a hapten or biotin, an enzyme such as a beta -galactosidase or horse radish peroxidase, a fluorescent radical, a phycobiliprotein, a luminescent radical, or a radioisotope. The probe can be used in assays of nucleic acids, taking advantage of the ability of the nucleic acid component to hybridize.
