The cells ended up grown to 80% confluence on the working day of transfection. The pEGFP-N1-Vpr encoding Vpr-GFP was transfected into focus on cells making use of jetPEI cationic polymer transfection reagent (Polyplus-transfection Inc., Illkirch, France). Human CD4+ T lymphoblast mobile line SupT1 was received from ATCC and developed in RPMI1640 medium supplemented with 10% FBS, 4 mM glutamine, on
