— Glutamyl, glutaminyl. aspartyl and asparaginyl tRNAs of calf brain were analysed by reverse phase chromatography for isoacceptor tRNAs. The radioactivity profiles revealed two peaks for gluta‐mate. three for glutamine, two for aspartate and one for asparagine. Comparison of brain tRNAs with tRNAs from other sources showed that glutamate and aspartate tRNAs of brain closely resembled a majority of other tRNAs in the number and relative abundance of isoacceptors. Glutamine and asparagine tRNAs from different sources exhibited more marked differences.
