Effect of IL-8 and GROα on the binding of [35S]GTPγS to membranes from CHO-CXCR1 (a) or CHO-CXCR2 (b) cells or of IL-8 in control or PTX-treated CHO-CXCR1 (c) or CHO-CXCR2 (d) membranes. Values are the means±s.e.mean of 3–9 separate determinations in duplicate. Vertical bars show the s.e.mean. In (c) and (d) the values are presented as a percentage of the basal in the PTX-treated membranes. The curves plotted through the data points are four parameter logistic equations fitted to the mean data.
