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 7–23 DNP molecules per 1000 bases are incorporated into the DNA. Hybridization experiments demonstrate that as little as 1.5 × 105copies of target DNA can be detected by filter hybridization with a photo-DNP-labeled probe and immunochemical detection.
