5'-end of oligoribonucleotides. These 5'-amino RNA oligomers may be readily conjugated to a variety of commercially available amine reactive fluorescent dyes, including succinimidyl ester derivatives. The synthesis, purification, and properties of 5'-pyrene-labeled RNA oligomers are described. These oligomers are shown to be unusually attractive probes for studies of oligomer-oligomer and oligomer-ribozyme
