Sodium dodecyl sulfate polyacrylamide gel electrophoresis(SDS- PAGE) analysis was used to identify red meat of various animal species. The protein profiles of whole muscle samples of different animal species after Coomassie- stained 12% gel showed different bands in different species. In all species (cattle, camel, horse, sheep, pig and dog), the molecular weight of the protein bands was ranged from 14.300 to 66.000 kDa, except camel, one prominent distinct band appeared above 66.000 kDa. In horse, the band pattern showing control distinct band at 34.7000. In sheep, pig and dog there were slight differences in their bands pattern which characteristic for each species. In conclusion, species speciation of meat can be done by SDS- PAGE and it is accurate, easy and comparatively rapid technique than many other methods which used for detection of adulteration of meat and meat product.
