Competitive binding to HEK tranfectants.

(A) Radiolabeled RANTES binding to CCR1/HEK cells, (B) radiolabeled I309 binding to CCR8/HEK cells. The log of total chemokine concentration is shown on the x-axis, while percentage of inhibition of specific radiolabeled chemokine is shown on the y-axis. The competitive effect of unlabeled LEC is shown with closed circles, unlabeled MIP1β is shown with closed diamonds, unlabeled RANTES is shown with closed boxes and unlabeled I309 is shown with closed triangles. The error bars mark the standard deviation for each point. This is representative of 3 experiments.
