Background and purpose: Cold storage results in clustering of gpIbα molecules on platelets. Consequently, the lectin domains of αMβ2 receptors on the liver macrophages recognize these molecules and ingest the platelets. Probably coverage of sugar molecules of gpIbα using galactose could prevent the recognition and ingestion of platelets by macrophages. The purpose of this study therby was to...

BACKGROUND Isolation of extracellular vesicles from plasma is a challenge due to the presence of proteins and lipoproteins.

AIM To develop a single-step protocol...
