Indian Muntjac Deer Skin Fibroblast Cells
The log phase monolayer culture of Indian Muntjac cells illustrated above was fixed, permeabilized, and blocked with 10-percent normal goat serum in phosphate-buffered saline prior to immunofluorescent labeling with rabbit primary antibodies to giantin, a protein resident in the Golgi complex of mammalian cells. The culture was subsequently stained with a mixture of goat anti-rabbit secondary antibody fragments (heavy and light chain) conjugated to Cy2. In addition, the specimen was labeled for the filamentous actin network with Alexa Fluor 568 conjugated to phalloidin and for DNA in the cell nucleus with Hoechst 33342. Images were recorded in grayscale with a 12-bit digital camera coupled to either a Nikon E-600 or Eclipse 80i microscope equipped with bandpass emission fluorescence filter optical blocks. During the processing stage, individual image channels were pseudocolored with RGB values corresponding to each of the fluorophore emission spectral profiles.
