High-performance liquid chromatography of transfer RNAs. Separation of transfer RNAs from mammalian sources

A survey of recent advances in high-performance liquid chromatography (HPLC) of tRNA is presented here. The polystyrene and reversed-phase anion exchangers are discussed for their ability to resolve tRNAs without loss of the aminoacyl-tRNA bond. The HPLC of a tRNA of choice, based on the affinity principle, is studied. Both chemical (boronate) and biological (plant lectins) affinity groups for the tRNA interaction are described. A comprehensive scheme is presented for the separation of four mammalian tRNAs. Scope of future research in this area is also discussed.
