Differential activation of the Fuc-T VIIreporter with Tax mutants.

Jurkat T cells were cotransfected with 4 μg reporter construct of theFuc-T VII promoter and 4 μg pCGTax/Tax mutants. Resultant activities are plotted as fold induction over that in the absence of Tax. Results are the mean values of fold induction for 3 independent assays normalized for CAT activity, and the corresponding standard deviation is indicated on the top of each bar.
