Infection of Cos-7 and 293 TT cells by HPV 31 and HPV 16 pseudovirions. (A). HPV 31 pseudovirions were used to infect Cos-7 cells (left panel) or 293 TT cells (right panel). (B). HPV 16 pseudovirions were used to infect Cos-7 cells or 293 TT cells (right panel). After 24 hours, the media was changed. The infection was allowed to proceed for a total of 72 hours where maximal GFP expression occurred. The cells were fixed and stained with DAPI. Shown is a representative field of infected cells detected by GFP fluorescence.
