Figure Lengend Snippet: Method validation for small EV (sEV) characterization isolated by size exclusion chromatography. (A) Determination of small EV (sEV)‐enriched fractions by nanoparticle tracking analysis and bicinchoninic acid assay. (B) 1. Western blotting analysis of small EV (sEV)‐enriched markers including CD81, CD63, and CD9 in small EV (sEV)‐enriched sample and positive control sample. 2. Western blotting analysis of contaminant protein including albumin, endosomal markers including Calnexin, GRP94 and loading control including GAPDH in small EV (sEV)‐enriched sample and positive control sample. (C) 1‐6 Transmission electron microscopy images illustrating morphology of small EV (sEV)‐ enriched sample ranging between 67‐138 nm. (A) Singular data points represent individual measurements of small EV (sEV) particle and protein concentration .
Article Snippet: Membranes were blocked with 5% non‐fat milk powder in PBS‐T (0.05% vol/vol Tween20 in 1xPBS) for 1 h. Blocked membranes were immunoblotted with CD81 (Novus Biologicals, USA, NB100‐65805, 1:1000, non‐reducing), CD63 (Novus Biologicals, USA, NBP2‐42225, 1:2000, non‐reducing), CD9 (Abcam, ab236630, 1:2000, non‐reducing), GAPDH (Abcam, ab9485, 1:2000, reducing), Calnexin (Abcam, ab22595, 1:2000, reducing), GRP94 (Abcam, ab3674, 1:2000, reducing), and Albumin (Novus Biologicals, USA, NBP1‐32458, 1:1000, reducing) overnight at 4°C.
