LXs and peptides specifically compete for 3H-LXA4 on HEK293 cells. ALXR-transfected HEK293 cells (5 × 106/ml) were incubated with 3H-LXA4 for 30 min at 4°C in the presence of an increasing concentration of unlabeled LXA4 (▪) or (A) ATLa1 (♦), ATLa2 (•), 15-deoxy-LXA4 (⋄), (B) MMK-1 (▵), MHC binding peptide (○), or SAA (♦). Bound and unbound radioligands were separated by filtration and specific binding was determined. Data represent the mean ± SEM from duplicates of n = 3.
