From: A mutant Tat protein inhibits infection of human cells by strains from diverse HIV-1 subtypes
NB-mCh inhibits Tat-mediated transactivation after infection of TZM-bl by different HIV-1 subtypes. TZM-bl cell lines expressing NB-mCh or mCh were infected with each HIV-1 strain or with mock supernatant. Luciferase activity was measured 48Â h post infection and normalized to total protein in the sample. Bars indicate mean percentage of transactivation inhibition by NB-mCh compared to mCh cells. Error bars indicate standard deviation of three independent experiments carried out in triplicate. The p value of the data set is shown
