Figure 8. Toxin binding and oligomerization.
A) Non-transfected ACHN cells, or cells transfected with shRNA specific for GAPDH or CAV2 were treated with GFP-labeled toxin. Whole cell lysates were analyzed by immunoblotting with GFP antibody. Non-transfected ACHN cells in the absence of toxin served as a control. A representative immunoblot is shown. B) Non-transfected ACHN cells, or cells transfected with a non-targeting shRNA or with CAV1-specific shRNA were treated with GFP-labeled toxin. Whole cell lysates were analyzed by immunoblotting with GFP antibody. Non-transfected ACHN cells in the absence of toxin served as a control. A representative immunoblot is shown.
