Electron microscopy of caveolae-associated filaments. a Immunogold labeling of vimentin along intermediate-size filaments (IF) in close contact with caveolae. b A high magnification image of intermediate filaments (IF) and a Ruthenium Red stained caveolae cluster. Arrows indicate putative protein linker molecules between the filaments and the caveolae. Bars 0.1 μm (a), 0.05 μm (b)
