Fresh platelets should always be used. Storing platelets dramatically changes the level of transmembrane proteins. The best way is to follow one of standardized protocols defined in: Immunophenotypic analysis of platelets. Krueger LA, Barnard MR, Frelinger AL 3rd, Furman MI, Michelson AD.Curr Protoc Cytom. 2002 Feb;Chapter 6:Unit 6.10.
This is done by flow cytometric analysis for detection of lack of GpIb/IX in Bernanrd Soulier syndrome (deficiency of CD42), and lack of GpIIb/IIIa in Glanzmann’s thrombasthenia (deficiency of CD41, CD61).
What is the best protocol for platelet glycoprotein (GPIIb/IIIa) analysis using flow cytometry?
