Analysis of CD63 surface expression in agonist-stimulated eosinophils.

CD63 surface expression in agonist-stimulated purified peripheral blood eosinophils was examined using flow cytometry analysis. (A) CD63 surface expression on resting eosinophils, (B) CD63 surface expression on IFN-γ–stimulated eosinophils, (C) CD63 surface expression on C5a/CB-stimulated eosinophils, and (D) CD63 surface expression on IL-3/IL-5/GM-CSF–stimulated eosinophils.
