Acetylated-α-tubulin in single myocyte and cardiac tissue. Confocal images of a a representative adult rat cardiomyocyte and b adult rat ventricular tissue, immunolabelled for acetylated α-tubulin. ‘N’ shows the nucleus. A fine network of cytoplasmic tubulin labelling is present in a, with dense labelling close to the nuclear regions shown by arrows. Arrowheads indicate intense tubulin labelling in between myocytes in extracellular spaces in the representative cardiac tissue section shown in b
