title: Determination of adenosine kinase activity by high-pressure liquid chromatography.
abstract: High-pressure liquid chromatography (reverse-phase mode) was used to assay adenosine kinase in cell and tissue extracts. The method is optimized for a rapid and selective analysis using 6-methylthiopurine riboside as substrate, isocratic elution and detection at 300 nm. A complete separation of substrate and product is achieved in about 3 min with no interference by other UV-absorbing compounds; the limit of detection is 20 pmoles.
