Figure 3.
SDS-polyacrylamide gel electrophoresis (SDS-PAGE) and western blot (WB) analyses of UEV yield after hydrostatic filtration dialysis (HFD) and differential centrifugation. Ten μg of protein was loaded in each lane and stained with colloidal Coomassie (A). Lane 1 HFDa; Lane 2, HFDa-P40; Lane 3 HFDa-P200 g; Lane 4 HFDa-SN200. Western blots were probed with antibodies against: (B) dipeptidyl dipeptidase 4 (DDP4); (C) Tamm–Horsfall protein (THP); (D) neprilysin (NEP); (E) programmed cell death 6-interacting protein (ALIX); (F) tumour susceptibility gene 101 (TSG101); (G) tetraspanin CD63 (R&D Systems antibody); (H) tetraspanin CD81 (R&D Systems antibody); (I) tetraspanin CD9 (Merck Millipore antibody); (J) tetraspanin CD9 (R&D Systems antibody); (K) Anti ApoA1, (L) β-actin. Molecular weights are expressed in kilo Daltons (kDa).
