Comparable platelet GPIb-IX expression between FcR γ-chain–deficient and wild-type mice.

Platelets from wild-type (upper panels) or FcR γ-chain–deficient (lower panels) mice were stained with phycoerythrin-labeled p0p4 (α-mouse GPIbα), fluorescein isothiocyanate–labeled p0p6 (α-mouse GPIX), or phycoerythrin-labeled JON1 (α-mouse GPIIb/IIIa), respectively. The fluorescence was analyzed by flow cytometry (solid lines). Gray lines represent the control, the fluorescence of rat α-mouse Ab. The results shown are representative of 4 experiments.
