a) Flow cytometry data from Y7092 expressing yeGFP-DDFKBP; untransformed Y7092 (red), YRR030 (Y7092 ho::PSOD1:yeGFP-DDFKBP::KANMX4 (blue), YRR030 + 5μM Shield-1 (green), YRR030 +100nM rapamycin (orange). YRR030 +1μM FK506 (green) is shown in the right panel, for clarity. b) Flow cytometry data from Y7092 expressing yeGFP-DDDHFR; untransformed Y7092 (red), YRR009 (Y7092 ho::PSOD1:yeGFP-DDDHFR::NATMX4)(blue), YRR009 + 100μM TMP (green). c) Flow cytometry data from NIH 3T3 cells; untransduced (red), transduced with YFP-DDDHFR (blue), transduced with YFP-DDDHFR +10μM TMP (green).
