Fig. 4. Relative protein abundance of MSTN immunoreactive protein (MIP) in white and red muscle from transgenic and size-control coho salmon. Abundance of the 42 kDa MIP (top) and the 14 kDa MIP (bottom). Values are means ± S.E.M. (N=8) at each sampling time. For each graph, bars that do not share identical lowercase letters are significantly different when compared separately within fish group (transgenic, size control) or tissue type (white muscle, red muscle) at P0.05.
