Results from Myosin heavy chain isoform average abundance (arbitrary units) and its percentage by ESI-Quadrupole-Orbitrap of the inflow and outflow segments of S. canicula (n=3) compared with a C. milii database. Both samples contain four sarcomeric isomyosins. The fast-twitch MYH2 and MYH6 are more abundant in the inflow segments whereas the slow-twitch MYH7 and MYH7B are predominant in the outflow segments. A small proportion (1-2%) of the non-sarcomeric isoforms MYH9, MYH10, MYH11 was found in both segments
