FIG. 3

(A) Subcellular localizations of wild-type Tax (WT) and truncation mutants in transfected HeLa cells were determined by immunofluorescence microscopy using an anti-Tax rabbit polyclonal antibody. (B) Cytotoxicity induced by Tax mutants was quantified by transient cell death assays. A CMV-Bax expression construct was included as a positive control for apoptosis. Results shown are representative of four independent transfections; error bars represent standard deviations.
