FRhK4 cells were co-transduced with LPV-treated HIV-LUC viruses Rescue of GFP infectivity was assessed by flow cytometry. Data are singlet % GFP values and two repeats of the experiment are shown. See also Appendix figure S3. Statistical analyses were performed using 2-way ANOVA with multiple comparisons. * P<0.05, ** P<0.01, *** P<0.001.
