Figure 5.
Concentration-koff relationship of ABA-X-BY630 dissociation in the absence and presence of competitive ligands at the A3-AR and A1-AR. Dissociation rate koff of 30 nM ABA-X-BY630 from CHO-A3 (A) and CHO-A1 cells (B) in the absence (□) or presence of XAC (■), NECA (○) and adenosine (●). Values for koff were derived from global analysis of dissociation kinetic data to a monophasic exponential decay.). Rate of perfusion was maintained at >12 complete fluid exchanges/min. Data points are expressed as means ± se from 3–11 separate experiments; each replicate represents the average of 10 cells.
