For HCMV infection, seed two 175-cm 2 flasks of 60% to 70% density, actively growing primary HFFs. For transfection, seed two 175-cm 2 flasks of HeLa cells, 25% to 30% density and actively growing cells. For best results, use HFFs at or less than passage 18 as primary HFFs undergo senescence following 50 cell doublings or ~25 passages.
