NB-mCh inhibits Tat-mediated transactivation after transfection of TZM-bl by Tat from different strains. TZM-bl cell lines expressing NB-mCh or mCh were transfected with pCDNA3.1+ containing each Tat variant or with empty pCDNA3.1+ A Gaussia luciferase expression plasmid was co-transfected as a control for transfections efficiency. Luciferase activity was measured 48Â h post transfection. Bars indicate mean percentage of transactivation inhibition by NB-mCh compared to mCh cells from two independent experiments each carried out in triplicate. The p value of the data set is shown
