Abstract
This paper illustrates the fractionation of cytoplasmic transfer ribonucleic acid from rat liver by reversed-phase high performance liquid chromatography using a gradient of acetonitrile/ammonium acetate. The procedure is fast, highly reproducible, and gives an excellent resolution of the numerous tRNA population: about 50 peaks with area peak percentages ranging from 0.001 to 5 can be monitored. Uncharged tRNA preparations exhibited a chromatographic profile different from aminoacylated tRNA, thus suggesting a possible strategy to distinguish between aminoacylated and nonacylated tRNA species. Moreover, a first approach to map the HPLC peaks was attempted by chromatographing preparations of tRNA which had been aminoacylated with individual 3H-labeled aminoacids. Here is reported the case of tRNA(Pro), which gave three well separated radioactive peaks, most likely corresponding to tRNA(Pro) isoacceptor species.
