This assay aimed to determine the serum protein--via polyacrylamide gel electrophoresis, which contained duodecil sodium sulfate (SDS-PAGE)--in 120 dogs, with different breeds and ages, seen by the Veterinary Hospital "Governor Laudo Natel." These animals were grouped into five experimental groups: Group 1--group control with 20 dogs, group 2-28 dogs with regenerative anemia; group 3 27 dogs with arregenarative; anemia group 4-10 dogs with primary immune-mediated hemolytic anemia (AHUM 1.rd); group 5-35 dogs with secondary immune-mediated hemolytic anemia (AHUM 2.rd). The technique allowed the SDS-PAGE fractionation of 24 protein, whose molecular weights (PM) ranged from 18,000 to 165,000 daltons (Da). The dogs with 1st and 2nd AHIM showed 24 protein fractions in their tracks electrophoretic, while other groups of dogs showed 23 fractions of protein, whose molecular protein weight of 68,000Da was not found. Thus, twenty-three proteins were common to proteinograms of the five experimental groups. From these, it was possible to identify eleven protein fractions nominally, and others were identified by their molecular weights. For control dogs, the anemic (groups 2, 3, 4 and 5) showed higher concentrations of serum transferrin and between them, the animals carrying the primary IMHA. All groups of dogs showed anemic levels of serum haptoglobin and phosphorylase significantly higher than the control dogs, while the serum ceruloplasmin was lower in anemic dogs. These findings provide additional information to the elucidation of the AHIMs in dogs.
