Surface expression of CCR1, CCR3, CCR5, CXCR1, CXCR3, and CXCR4 on platelets assessed by fluorescence-activated cell sorter analysis.

Surface expression of GPVI, a collagen receptor, is shown for comparison. Platelets were labeled with 10 μg/mL antireceptor antibody (black line) or an isotype control antibody (or preimmune polyclonal) (gray filled), then labeled with an fluorescein isothiocyanate (FITC) conjugate. Washed platelets were analyzed by flow cytometry and accumulated events were gated against the isotype control. The experiment shown is representative of 3 similar experiments.
