Immunofluorescent (IF) evaluation of changes in surface marker expression—CD41 (a), CD62P (b), and CD63 (c)—in Ca2+-stimulated platelets. PLT platelets. Washed platelets were treated with 0.1% CaCl2 in culture dishes and subjected to IF staining. Similar results were obtained from samples of three other donors
