Simultaneous light and electron microscopic observation of immunolabeled liver 27 KD gap junction protein on
We report on immunolabeling of gap junction protein in rat liver. Simultaneous light and electron microscopic immunolabeling of ultra-thin frozen sections was performed to confirm that the antigenic targets of polyclonal antibodies and a monoclonal 27 KD antibody (12/1 C5) are the gap junctions. Our results clearly demonstrate that the immunoreactive sites determined by indirect immunofluorescence correspond to immunogold-labeled gap junctions identified in the same section according to electron microscopic criteria. Our results also support the concept that the 27 KD protein is a major constituent of gap junctions.
