Identification of the muscular proteins of pigs submitted to the eletroforesis in polyacrilamide gel with Sodium Dodecyl Sulfate (SDS)

Abstract

Fragments of two pigs muscles of Landrace, Large White, Duroc purebred and crossbred, the eletroforesis was submitted in polyacrilamide gel with SDS, being objectified to verify there would be a specific pattern for pigs and to identify through the molecular weights, the main proteins. The results show that there would be a specific pattern for swine and they were identified miosina heavy chain, actina, troponina, tropomiosina and a light chain of miosina.
