Immunofluorescence bisBenzimide H 33342 trihydrochloride: Cat. No. 14533: Septins are small GTPases that localize in a filamentous pattern in cells. Treatment of cultured Human podocytes with cytochalasin D disrupts the filamentous organization of the actin cytoskeleton, as visualized by phalloidin staining (red). In cytochalasin D-treated podocytes, the normally linear septin 7 filaments (green) curl and form ring-like structures, indicating that septin 7 localization depends on an intact actin cytoskeleton. The nucleus is visualized with DAPI (blue). Submitted by A. Wasik, University of Helsinki.
