Figure Lengend Snippet: EVs glycoprotein enrichment and proteomic analysis. (A) Workflow for proteome identification of EV total proteins and glycoproteins. (B) Principal component analysis of 95C and 95D EVs total proteins (T‐p) and glycoproteins (G‐p). (C) Venn diagram of EVs total proteins and glycoproteins. (D) Pearson correlation coefficient matrix plot of multiple groups. The correlation coefficient was represented by a color scheme from white (negative correlation) to blue (positive correlation). (E) The volcano plot represents the quantitative analysis of N‐glycoproteins in 95D EVs versus 95C EVs. Orange represents proteins that were at least 2‐fold upregulated ( p < 0.05); blue represents proteins that were at least 2‐fold downregulated ( p < 0.05). (F) Distribution plot of the number of N‐glycosylation sites of 95C and 95D EVs. (G‐I) Comparison of the ranking, relative quantity, and unique peptides of three typical glycoproteins before and after ConA enrichment. GO analysis (J) and KEGG pathway enrichment (K) of differentially expressed glycoproteins in EVs. BP, biological process; CC, cellular component; MF, molecular function.
Article Snippet: Briefly, for 1 mg EVs protein, 1 mL of agarose bound lectin ConA (Vector Laboratories, AL‐1003) was packed into a 2 mL disposable screw end‐cap spin column with filter (Thermo Fisher Scientific, Waltham, MA, USA).
