Determination of erythrocyte adenosine triphosphate by liquid chromatography

A method for measuring erythrocyte adenosine triphosphate utilizing anion exchange high-pressure liquid chromatography is described. The method is not subject to interferences inherent in methods involving hexokinase or the firefly system. The method is highly sensitive, reproducible and rapid. Adenosine diphosphate and adenosine monophosphate can also be analyzed if desired.
