Fig. 9. Western analysis of NM2A and NM2C expression in myoblasts (MB) and 3 day myotubes (MT). Western analysis shows a positive band of the correct size for NM2A in myoblasts and myotubes. By contrast, despite using a longer exposure time (and hence higher background), a positive band of the correct size for NM2C was only observed in myotubes and not in myoblasts. Protein loading in each of the lanes was the same.
