Mice lacking GPR56 are delayed in forming occlusive thrombi in the carotid artery. (A) Mouse carotid artery FeCl3-induced thrombosis assay showing times to reach full vessel occlusion in genetically identical recipient mice injected with calcein-AM–labeled Gpr56+/+ or Gpr56−/− donor platelets. Error bars are the mean ± SEM (n = 6). (B) Representative still images showing progression to full vessel occlusion that accompany Movie S3. **P < 0.005.
