Figure 1

Photomicrographs of serial sections of m. longissimus dorsi of carriers (A, B, C) and non-carriers (D, E, F) of the PRKAG3 mutation. Fibre types I, IIA, and IIB classified with myosin ATPase (pH 4.6) stains (A, D) and fibre type IIAX is classified with immunohistochemical (A4-74) stains (B, E). Note that many type IIB fibres in the myosin ATPase stain were classified as IIAX fibres with the immunohistochemical stain and that some of these IIAX fibres may be pure, IIX or IIBX fibres. Oxidative capacity is evaluated from the NADH tetrazolium reductase stains (C, F). Note that type I fibres have a high staining intensity, whereas staining intensity varies among the subgroups of type II fibres.
