Comparison of Continuous and Strip Paper Electrophoresis Technics for Study of Serum Glycoproteins.∗

A continuous paper electro-phoretic technic was compared with a paper strip electrophoretic technic as a tool for the study of serum protein and glycoprotein fractions. Protein and glycoprotein for the continuous electrophoretic study were quanti-tated by analyses of the fractions by the biuret and tryptophan reactions. The glyco-proteins by the strip technic were quantitated by the periodic acid Schiff reaction and the protein strips by the bromophenol blue staining. In both cases the strips were evaluated with an automatic photoelectric scanner. Good agreement between the two methods for both protein and glycoprotein was noted.
