The purine and pyrimidine bases of E. gracilis have been separated using a high-pressure liquid chromatograph (HPLC). Each base was unambiguously identified by its characteristic elution profile and UV absorption spectrum. This method allows for the study of the base composition of mRNAs altered by

β¦ Synopsis
An analytical method is presented for the quantitative determination of certain major and modified bases in unfractionated rat liver transfer RNA (tRNA). tRNA was hydrolyzed with perchloric acid, and the liberated bases were separated by high-pressure liquid chromatography. Bases were selectively detected in tRNA hydrolysates at wavelengths near their uv-absorption maxima. Recovery values for individual bases generally were in the 80-100% range. The composition of rat liver tRNA with respect to 10 bases was determined. and the levels ofthese bases were in agreement with published values determined by other methods.
