Fig. 3. XCR2 facilitates XNR1 and derrière signaling. 293T cells were transiently transfected with the A3-lux luciferase reporter. Luciferase activity was normalized to the activity of co-transfected ß- galactosidase and then expressed as the fold difference in activity relative to that of FAST1 transfection. The average of three independent examinations in triplicate is shown. Error bars show s.d.
