Background: Platelet microparticles (PMPs) and their abundance in the blood are a prognostic biomarker in thrombotic disorders and cancer. Nanoscale flow cytometry (nFC) is ideal for high-throughput analysis of PMPs but these clinical assays have not been developed previously.
Objective: This article demonstrates that nFC is a suitable technology to enumerate PMPs present in plasma samples in a clinical setting.
Background: Platelet-derived extracellular vesicles (PL-EVs) are present in plateletpheresis concentrates (PCs) and may influence the quality of PCs. The aim of the study was to analyze PC-derived PL-EVs and to correlate them with standard quality control (QC) variables of PCs and with donor-specific laboratory variables.
Study Design And Methods: PL-EVs were analyzed by standard as well as advanced high-sensitivity flow cytometry (FCM) and nanoparticle tracking analysis.
