High-performance liquid chromatographic assay for identification and quantitation of nucleotides in lymphocytes and...

A method for the identification and quantitation of nucleotide pools in lymphocytes and leukemic blasts is described. Separation of these metabolites was performed by anion-exchange high-performance liquid chromatography using a pH and concentration gradient consisting of several linear steps. The mono-, di- and triphosphates of adenosine, cytidine, guanosine, inosine, uridine and xanthosine could conveniently be separated together with NAD+, cyclic AMP, NADP+ and uridinediphosphoglucose (UDPG). In addition, data on the accuracy and precision of the method are given and its potentials for use in the analysis of nucleotide pools in leukemic lymphoblasts are illustrated.
