Effect of 3-APS on tau-actin complexes. As indicated in Figure 1, tau expresing HEK cells show some lamellipodia regions that are stained by both, phalloidin (aggregated actin) and tau antibodies. The merged picture is also indicated. DAPI was used for nuclei staining (A). In the presence of 200 μM 3-APS, the phalloidin and Tau staining clearly decreases (B).
