Abstract
The concentrations of radioactive and nonradioactive purine bases, purine nucleosides, purine mono-, di-, and trinucleotides in acid extracts of fibroblasts were determined by anion-exchange column chromatography. The concentrations of nonradioactive components were determined by computerized integration of the signal from a double-beam uv-detector. The radioactive metabolites were quantitated by high-efficiency, continuous liquid scintillation counting, employing a discrete sample transport system.
