From: A simple and available measurement of onco-sEV dsDNA to protein ratio as a potential tumor marker
CEA magnetic bead antibody can effectively capture CEA + sEVs in cell supernatant and serum
(A) mRNA expression of CEA in the four cell lines. (B) Protein expression of CEA in the cell lysates and sEVs. (C) Statistical analysis of CEA protein expression. (D) NPr of cell sEVs before and after enrichment of CEA magnetic bead antibodies. (E) NPr of serum sEVs before and after enrichment of CEA magnetic bead antibodies. (F) NPr of serum without sEVs.
