Figure 1.

Expression of FcγRIIa by platelets from 33 patients with ESRD undergoing hemodialysis. Expression of FcγRIIa was determined with the use of flow cytometry. FcγRIIa MFI was quantified by subtracting the mean fluorescence intensity (MFI) seen with secondary antibody alone from the MFI seen with both the primary and secondary antibody. A skewed distribution is apparent with 50% of the patients exhibiting low expression (MFI<1.2).
