“…135 Older literature and sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE)based studies can also be found for tilapia, vundu, and catfish, among other species. [136][137][138] A representative electrophoretogram of a moray eel is shown in Figure 7. Overall, it appears EPH studies of teleost species can reflect changes with a variety of inflammatory stimuli.…”

EPH can provide information regarding serum or plasma proteins, including albumin and globulins, that can be broadly classified based on their migration. The globulin fractions can reveal inflammation as well as polyclonal and monoclonal gammopathies. Detection of the latter, also named paraproteins, is one of the most common applications of EPH in human medicine as clinicians have a large toolbox of specific assays for various acute-phase proteins (APPs) that allow them to more specifically gauge inflammation. 1,2 In veterinary medicine, given the advances in species-specific and cross-reactive reagents for major APP in traditional species, including dogs, cats, and horses, these tools can complement the use of EPH in its valid quantitation of albumin and detection of paraproteinemia. [3][4][5][6][7][8] In non-traditional species, including birds, reptiles, fish, amphibians, invertebrates, small exotic mammals, and non-domesticated mammals, EPH can also be used as an aid to the diagnosis of lymphoproliferative disease, but its primary use is in the detection of inflammation and polyclonal gammopathies. For many of these species, reagents are not yet available or widely validated to quantitate APPs. The valid quantitation of albumin, a key negative APP, by biochemistry analyzer methods, remains a major issue. Moreover, in non-mammalian species, as innate immunity is perhaps the essential, diverse, and robust immune response, EPH can provide even more value. 9,10 Challenges in the applications of EPH in these special species include a lack of standardization of fraction delimiter placements, RIs, and information regarding fraction composition. This paper reviews the applications of EPH in non-traditional species as well as the currently available methodology. Additional reviews on this subject with a varied focus are also available.

“…As found by other authors using SDS-PAGE, the presence, position and amount of protein in serum fractions can be affected by pollutants, water quality and phylogenetic distance (20,(32)(33)(34)(35)(36). Gicking et al (37) states that plasma protein electrophoresis may be useful as a health assessment tool for evaluating injured sea turtles.…”

The electrophoretic profile of serum proteins was investigated in juvenile Piaractus mesopotamicus and Salminus brasiliensis fed with diets containing bovine colostrum, a nutraceutical food, in lyophilized form (LBC) for either 30 or 60 days. Materials and Methods: Blood samples were collected from juveniles of P. mesopotamicus and S. brasiliensis fed for either 30 or 60 days with diets containing 0%, 10% or 20% of LBC. Serum protein fractions were then determined by electrophoresis in agarose gel. Results: The P. mesopotamicus, an omnivorous fish, showed six serum protein fractions, while the S. brasiliensis, a carnivorous fish, showed four serum protein fractions. In both species the albumin fraction showed higher protein content at 30 days than at 60 days (p<0.05), indicating an inverse relationship with growth. The 5 th and 4 th fraction in mobility from the P. mesopotamicus and S. brasiliensis serum, respectively, were positioned in a gamma-globulin zone. In P. mesopotamicus, the concentration of protein in the gamma-globulin zone was higher at 60 days than at 30 days (p<0.05). In S. brasiliensis, in turn, the concentration of protein in the gamma-globulin zone was higher at 30 days than at 60 days (p<0.05). In juvenile P. mesopotamicus, a higher concentration of protein was also observed in the gamma-globulin zone in the 0% LBC compared to 10% and 20% LBC (p<0.05). Thus, the feeding period influenced only the fractions that were positioned in the albumin and gamma-globulin migration zone in both species. Conclusion: The consumption of bovine colostrum decreased the concentration of protein in gamma-globulin fraction of the P. mesopotamicus, indicating that these juveniles had either less stimulus for their own synthesis of defense elements or an immunosuppressive effect of bovine colostrum ingestion.
