Transductions were performed by placing a 1:5 dilution of the Moloney murine leukemia virus (MLV)-GFP or lenti-GFP supernatant over the cells for 24 hours.
Cells were plated in improved minimum essential medium (IMEM) and 10% fetal calf serum (FCS) for 48 hours before transduction and grown for 72 hours after transduction.
Cells were grown to confluence in IMEM-10% FCS, serum was then deprived with 0.1% FCS, and liquid media were supplemented for 72 hours before transduction. They were maintained for another 72 hours under the same conditions after transduction before analysis.
Cells were grown in IMEM-10% FCS. After 48 hours, the medium was supplemented with aphidicolin 15 μg/mL 24 hours before, for the duration of transduction, and for 72 hours after transduction.
