Characterization of OEV, DN and DN@OEV. (A) TEM images of OEV, DN and DN@OEV. (B) The size distribution of DN, OEV, and DN@OEV determined by DLS. (C) The expression of CD81, CD9, and calnexin of OEV and DN@OEV as measured by Western blotting using SKOV3 lysates as a control. (D) The stability of DN, OEV, and DN@OEV in 10% FBS determined by DLS. (E) The release curve of DN and DN@OEV in PBS solution with pH 7.4 and pH 6.5 determined by UV spectrum. The data are shown as mean ± SD (n = 3).
