Summary

Hypoxanthine incorporation was studied in growing HPRT mutant cells by preincubating them with extracts from normal cells, HPRT mutant cells, and extracts of their lyophilized cell sediment. HPRT mutant cells showed no increase of hypoxanthine uptake after preincubation with extracts of mutant cells, whereas after preincubation with extracts from normal cells and lyophilized sediment of HPRT mutant cells the incorporation rate was increased. This effect could not be observed when normal cells were preincubated with extracts of lyophilized sediments of normal cell lines.
