A human promyelocytic leukemia cell mutant (HL-60-AR) with deficiency in HGPRT and resistance to 8-AG was established by treat〓nt of the HL-60 cells with MNNG and prescreened in 0.3% agar RPMI-1640 semisolid medium containing 8-AG. The mutant cells show the following characteristics:(1) resistant to cytotoxic action of 8-AG and growing vigorously in medium containing 20ug/ml 8-AG;(2) capable of forming 〓〓 colonies in soft agar medium in the presenee of 8-AG:(3) highly sensitive to HAT selective medium and fail to growing in HAT medium of form colonies in soft agar medium containing HAT;(4) completely deficinet in HGPRT activity; and (5) no radioactive silver grains over the mutant cells due to the absence of -hypoxanthine incorporation showed by radioautography.
