Figure 2: Western blot immunodetection of cardiac MyHC isoforms from left ventricle (LV) homogenates and extracts of adult euthyroid (EU), hypothyroid (HY), and hyperthyroid (TH) Lewis rats. The membranes were stained by NB300-284 antibody recognizing both MyHCα and MyHCβ isoforms (a) or by BA.G5 antibody, which was solely specific for cardiac MyHCα isoform (b).
