Figure 4.
Rb9 interacts with and is internalized by bone marrow derived dendritic cells (BMDCs). Panels are representative confocal images of bmDCs stained with DAPI (blue, panel 1) and phalloidin (red, panel 3) for nucleic acid and filamentous actin staining, respectively. Biotinyl-Rb9 is stained with FITC (green, panel 2). A merge of 1, 2, and 3 can be seen on panel 4. FITC-biotinyl-Rb9 colocalizes with DAPI in a nuclear region (panel 5) and peripherally with phalloidin (panel 6) as shown by white and yellow points/areas in the cellular cytosol on both colocalization panels. Bars = 10 μm.
