Abstract
A solid support capable of binding a nucleic acid thereto upon suitable irradiation, comprising (a) a solid substrate, (b) a member selected from the group consisting of a furocoumarin, a phenanthridium halide, and photochemically reactive derivatives thereof, and (c) a divalent radical chemically linking the substrate and the member (b). Specifically, a hydroxy group-containing solid substrate such as nitrocellulose paper is linked via a bifunctional reagent such as cyanogen bromide or 1,4-butanediol diglycidyl ether to an amino-substituted angelicin or psoralen or phenanthridinium bromide which in turn is photochemically linked to a nucleic acid. This is capable of hybridizing with other nucleic acid fragments and is thereby useful in diagnostic assays.
