WebDetermination of PS exposure in PRBCs Aliquots were aseptically sampled from PRBC units and centrifuged (5 min at 1000 g). Pelleted erythrocytes were washed 3 times in phosphate buffered saline (PBS) by centrifugation (5 min at 1000 g ), and the supernatants discarded. WebIt is currently unclear why agonist-stimulated platelets require shear force to efficiently externalize the procoagulant phospholipid phosphatidylserine (PS) and release PS-exposed microvesicles (MVs). We reveal that integrin outside-in signaling is an important mechanism for this requirement.
