Canine Serum Protein Patterns Using High-Resolution Electrophoresis (HRE)

Serum protein values were determined in 26 healthy dogs using agarose gel electrophoresis (SPE), splitting the electrophoretic separation into six regions: albumin, α1, α2,β1, β2and γ globulins. High-resolution electrophoresis (HRE) was used to separate single proteins. Serum proteins from dogs (26 healthy and 20 affected by various diseases) were then characterized by electrophoretic immunofixation (IFE) and Sudan black staining on HRE film. Haemoglobin and normal canine plasma and serum were used to identify haptoglobin and fibrinogen, respectively. standard pattern, determined by HRE, the following proteins were identified: albumin, α1-lipoprotein (α1-region), haptoglobin andα2 -macroglobulin (α2-region), β -lipoprotein and C3 (β1-region), transferrin and IgM (β2-region), IgG (mostly in γ -region and partly in β2-region). The HRE pattern shown by healthy dogs could be compared with those of dogs affected by various diseases to obtain clinical information.
