Human L-, P- or E-selectin/μ chimeras bind to human, bovine, pig or rat neutrophils. Neutrophils were incubated with saturating concentrations of human L-, P- or E-selectin/μ chimera (filled histogram). Chimera binding was abrogated by 10 mM EDTA (open histogram). The percentage of positive cells and the mean fluorescence intensity are indicated in each histogram. Histograms are representative of 2–3 experiments.
