Adenosine has been measured at the nanomolar level by an enzymatic radioactive assay. The nucleoside is converted into [U-14C]ribose-labeled inosine via the following reactions: adenosine + H2O----adenine + ribose (adenosine nucleosidase); adenine + [U-14C]ribose 1-phosphate in equilibrium with T[U-14C]ribose-adenosine + Pi (adenosine phosphorylase); [U-14C]ribose-adenosine + H2O----[U-14C]ribose-inosine + NH3 (adenosine deaminase). The radioactivity of inosine, separated by thin-layer chromatography, is a measure of the adenosine initially present.
