Multiple labeling of cellular constituents by combining surface reflection interference and fluorescence microscopy.

In this paper the technique for visualizing cytoskeleton in detergent-extracted cultured cells by surface reflection interference (SRI) microscopy after staining with the protein dye Coomassie Brilliant Blue (SRI-CooB technique) is used in conjunction with fluorescently-labeled antibodies or with other fluorescent probes to detect a number of constituents in the same cultured cell. Because SRI-CooB technique preferentially visualizes microfilament bundles along the ventral aspect of cells adhering to a glass substratum, we feel that this simple and rapid technique has great potential in studies of cell-substratum adhesiveness and of adhesion-related cytoskeletal organization.
