we have now examined smooth muscle tissue of different blood vessels ( e.g. , aorta , small arteries , arterioles , venules , and vena cava ) from various mammals ( man , cow , pig , rabbit , rat ) by one- and two-dimensional gel electrophoresis of cell proteins and by immunofluorescence microscopy using antibodies to different intermediate-sized filament proteins .
