drug levels in p388/r cells treated in vitro with adr ( 1-10 micrograms/ml ) were twofold to fourfold lower than were levels in similarly treated p388/s cells fcm analysis of p388/s and p388/r cells exposed in vitro to adr showed qualitative and quantitative differences in adr fluorescence profiles of drug-treated cells ( 1-5 micrograms/ml ) but not of the isolated nuclei ( 0.5- 10 micrograms/ml ) .
