A photoactivatable reagent for introducing haptens onto DNA probes has been prepared using a commercially available bifunctional linker arm reagent and amino-derivatized 2,4-dinitrophenyl (DNP). The resulting compound (photo-DNP) couples efficiently to DNA using an ordinary sunlamp. Under optimum conditions, about
