Using flowcytometry, we investigated platelet membrane expression of CD62P, CD63 in platelet stored for up to 3 days under standard blood banking conditions. Leukocyte reduction of platelet before transfusion is a routine procedure in many blood transfusion centers to prevent leukocyte side-effects. Twenty-four platelet units prepared by platelet-rich plasma were processed by in-line leukdepletion using an LRP10SE-Pall filter. The filtered and unfiltered platelet concentrates were compared during storage for CD62P, CD63 markers and pH. During storage for up to 3 days, leukdepleted platelet units displayed no significant pH difference in comparison with routine platelet preparation (P>0.05). During storage for up to 3 days (1, 3 days) leukdepleted platelet units displayed a decrease in the CD62P and CD63 expressions as compared with routine platelet preparation (P SP - 97 EP - 106 AU - Solaimani Ferizhandy, A AU - Aghaee Pour, M AU - Pourfatollah, A.A AD - KW - 1) Prestorage Filtration 2) Platelet-Rich Plasma 3) CD62P 4) CD63 UR - http://rjms.iums.ac.ir/article-1-435-en.html ER -
