Analysis of serum proteins by agarose gel and capillary electro phoresis

Electrophoresis is a basic technique used to identify disorders of blood serum protein fractions. Agarose gel is the most frequently used medium for routine protein separations. However, capillary electrophoresis seems to be an attractive alternative to gel electrophoresis. The article presents the results of comparative analysis of two systems (Sebia): Hydrasys designed for electrophoretic separations on agarose gel and Minicap for capillary electrophoresis. The purpose of study was to evaluate comparatively the concentrations of each serum protein fraction obtained by gel and capillary electrophoresis and to analyze the correlations between the results obtained by those two systems depending on the concentrations of each protein fraction. The study was carried out in the group of 98 patients, 46 females and 52 males. Despite slight quantitative differences in certain fractions obtained by both methods, capillary electrophoresis offers a fully automatic process of analysis, high speed and efficiency which proves that capillary electrophoresis is appropriate alternative to gel electrophoresis.
