Novel photolabile photochemical reagents are disclosed. The reagents are useful in a variety of biochemical and chemical contexts, including nucleic hybridization assays and chemical phosphorylation of hydroxyl-containing compounds. The reagents are particularly useful for introducing cleavable sites into oligonucleotide or polynucleotide chains, i.e., sites which are cleavable upon photolysis. The reagents are also useful in both 5'- and 3'-phosphorylation of oligonucleotide or polynucleotide chains. |
