B. Representative flow cytometry plot of intracellular HIV-1 Gag protein staining (KC57) versus side scatter (SSC) in JØ and J34c cells, mock infected or infected with HIV-1NL4-3, after 48 hours of culture and corresponding fold change (J34c/JØ) plot in four biological replicate assays. Differences to control were found to be significant with a paired two tailed t test (p0.05).
