A photochemical nucleic acid-labeling reagent of the formula ##STR1## wherein Q is a photoreactive residue of a nucleic acid-binding ligand; L is a detectable label residue; R is hydrogen, C.sub.1 to C.sub.7 -alkyl, aryl, hydroxy, or C.sub.1 to C.sub.7 -alkoxy; x is an integer from 2 through 7; and y is an integer from 3 through 10; wherein R and x, respectively, can be the same or different each time they appear in the formula. The reagent is useful in the highly efficient labeling of nucleic acids for the purpose of detection in hybridization assays.
