6′SLN
6′SLN is a cancer-related extracellular vesicle (EVs) surface glycan that serves as a key form of protein glycosylation in EVs. 6′SLN is also a sialic acid derivative that can interact with hemagglutinins (HAs) from human and avian influenza virus strains, making it useful for research into anti-influenza dr_ugs.
