Fig. 2. Expression and localization of DP and desmin in monkey cardiomyocytes was detected by immunofluorescence microscopy (A-C). Desmin was stained with a rabbit antiserum (A) and DP with a monoclonal mouse antibody (B). The two proteins codistribute at intercalated discs, whereas desmin is also found along the cardiac muscle striations (C). Bar, 5 µm.
