Molecular analysis of Tripterygium hypoglaucum (level) Hutch-induced mutations at the HPRT locus in human promyelocytic leukemia cells by multiplex polymerase chain reaction.
We have measured the forward mutation rate at the hypoxanthine phosphoribosyltransferase (HPRT) gene of the human promyelocytic leukemia cell line HL-60 and have determined the molecular spectrum of spontaneous HPRT mutations in 45 independent 6-thioguanine-resistant HL-60 sublines.
