Terminology in the purchasing file
Exosomes are a subset of extracellular vesicles in the research literature. Commercial catalogs sometimes use the terms loosely—record the supplier's exact label language.
Ask which characterization methods support any particle claims.
Why precise language matters
Loose synonyms create mismatches between ads, consents, and lot documents. Align public language to the label.
Avoid stem cell exosomes framing that invites live-cell and disease implications these products should not carry.
