The expansive cellular microtubule network present in a culture of Indian Muntjac fibroblasts (illustrated above) was immunofluorescently labeled with primary anti-tubulin mouse monoclonal antibodies and rabbit anti-giantin polyclonial antibodies followed by goat anti-mouse Fab fragments conjugated to Rhodamine Red-X and Alexa Fluor 647, respectively. The culture was also counterstained for DNA in the cell nucleus with Hoechst 33342. Images were recorded in grayscale with a Hamamatsu ORCA-AG camera system coupled to an Olympus BX-51 microscope equipped with bandpass emission fluorescence filter optical blocks provided by Semrock. During the processing stage, individual image channels were pseudocolored with RGB values corresponding to each of the fluorophore emission spectral profiles.
