Sun, Tsieh, Chan, Shiu-kee, and Gross, Stanley: Evaluation of a high-resolution electrophoresis system. Am J Clin Pathol 67: 247–250, 1977. A high-resolution electrophoresis system (Panagel) is evaluated by comparing the results with Microzone electrophoresis and with quantitation of individual protein fractions by the radial immunodiffusion technic and by the SMA system. The high-resolution electrophoresis showed a higher percentage of gamma globulin and a lower percentage of albumin than the Microzone system, with the alpha-1, alpha-2, and beta globulins being similar in quantity. The eight protein fractions studied: albumin, alpha-1 antitrypsin, alpha-2 inacroglobulin, haptoglobin, beta-lipoprotein, C3 complement, and gamma globulin, correlated very well with the corresponding components in the various methods used. The normal values of the protein fractions were determined.
