Fig. 3.

Luciferase activity induced by baboon DQA1 promoter haplotypes in a transient transfection reporter assay. Bars represent luciferase activity of 12 different baboon DQA1 promoter constructs calculated as the ratio of firefly to Renilla (coreporter) luminescence. Error bars represent standard error of the mean estimated from three replicate experiments. Numbers on the x axis correspond to the unique baboon DQA1 promoter haplotypes, and “Empty” refers to the promoter-less pGL3 basic reporter construct.
