Ion-pair reversed-phase high-performance liquid chromatography (HPLC), which has previously been used to fractionate double-stranded DNA molecules, can be applied to single-stranded RNA molecules in the size range of 200-1000 nucleotides. This procedure permits RNA molecules to be separated and recovered rapidly in liquid medium, thereby facilitating recovery. We have used this system to separate an in vitro transcription product containing a group I intron ribozyme from the intermediates and products of the splicing reaction, permitting rapid assay of ribozyme activity without the use of radioactivity.
