Embryonic Swiss Mouse Fibroblast Cells (3T3)

A culture of 3T3 cells was immunofluorescently labeled with primary anti-tubulin mouse monoclonal antibodies followed by goat anti-mouse Fab fragments conjugated to the cyanine dye, Cy3. In addition, the cells were simultaneously probed for DNA with the ultraviolet-absorbing probe DAPI, and for the cytoskeletal filamentous actin network with Alexa Fluor 488 conjugated to phalloidin.
