(A) Schematic representation of the sEVs isolation process using differential ultracentrifugation. (B) Western blot analysis for sEV-specific marker proteins, namely CD63, CD81, and TSG101, as well as the negative marker, Calnexin. (C) Morphology of the four sEVs types observed under TEM. (D) NTA analysis of the four sEVs types revealed similar size rangesBack to article page
