Expression of LIVP-GFP viral protein in various cell lines. The flow cytometry data. a Cells were infected with LIVP-GFP (MOI 1), and the percentage of GFP-positive cells was evaluated 24 h (grey bars) and 48 h (dark grey bars) post infection (hpi). GFP-positive cells were those with fluorescence intensities at least twice that of the autofluorescence intensities of non-infected cells. b Mean fluorescence intensities of the cell population infected with LIVP-GFP at MOI of 1 (grey bars) and MOI of 10 (dark grey bars) in comparison with the control cells at 24 hpi. c The original images of flow cytometry showing development of LIVP-GRF infection in tumour cells 2 and 24 hpi
