Electroforesis pattern of the proteins of swine skeletel muscles

Resumo

Electroforesis of total protein samples from the external obturador and long muscle of the neck of Landrace, Large White, Duroc purebred and crossbred swine was conducted in polyacrilamide gel (PAGE) at 10%, to verify the existence of a specific eletroforesis pattern that might serve to control possible frauds in meats and processed pork products. The results confirmed the existence of a specific electrophoresis pattern for total proteins of skeletal muscle of swine, that is not altered in the various genetic groups and in the two muscles studied.
