Abstract

Transfer ribonucleic acid is well fractionated on columns of arginine-agarose, whose properties appear in general to be similar to those of DEAE-Sephadex. However, the amino acid acceptor species are separated into sharper peaks and in several instances, notably for methionine, glycine, serine, leucine and aspartate accepting tRNAs from Escherichia coli, isoaccepting species are well resolved. In the case of methionine accepting tRNA from E. coli the tRNA Met-m species is eluted before the tRNA Met-f species and since it is also eluted prior to the bulk of the tRNA it is obtained in a high degree of purity. By comparing the properties of columns of arginine-agarose and its methyl ester in which the carboxylate anion is blocked, it is seen that the carboxylate ion plays a role in the fractionation of the tRNA Met species.
