The Application of UV-Radioactivity High Performance Liquid Chromatography to the Study of Hypoxanthine Transport in Human Erythrocytes

Abstract

A procedure is presented for the simultaneous measurement of concentrations of labeled and non labeled hypoxanthine by HPLC in order to study hypoxanthine transport in erythrocytes. A radioactivity detector connected on-line to the high performance liquid chromatograph in series with a UV detector provides on-line quantitative monitoring of hypoxanthine in erythrocytes or incubation medium. The procedure provides a rapid, sensitive and convenient means for the study of hypoxanthine transport.
