Abstract A method for starch gel electrophoresis of hemoglobins is presented in which a modified Lintner starch is used for the preparation of the gel. A discontinuous buffer system of tris-EDTA-borate/barbital is used as the electrolyte medium because of its superior resolving power. Hemoglobin A2 values, obtained with this method, of healthy individuals, patients with thalassemia, and those with various anemias of nonthalassemic origin are presented.

Abstract In a local colony of random-bred Albino rats, three different patterns of hemoglobin, arbitrarily denoted as patterns I, II and III, were detected by means of starch-gel electrophoresis in a discontinuous buffer system. Mating experiments showed that rats bearing pattern I and pattern III hemoglobin bred true. Crosses of pattern I with pattern III animals yielded only pattern II animals, and when the latter were mated inter se, the resultant F2 generation showed approximately a ratio of 1:2:1 for patterns I, II and III, respectively. When F1 animals from pattern I with pattern III crosses were mated back to animals of either parental type, the resultant ratio was found to be one pattern II: one pattern I or pattern III.

Heterogeneity of the group-specific (Gc) components in normal human serum has been demonstrated by the use of a lithium borate buffer system in conventional vertical starch gel electrophoresis and by prolonged immunoelectrophoresis in agar gel. In both Gc 1-1 and Gc 2-2 phenotypes a protein component migrates ahead of the main band. Immunological evidence indicates that the faster migrating band contains Gc specificity. The possibility that the two electrophoretically distinct Gc components share a common polypeptide chain is discussed.

SummaryWhen urea or ε-amino caproic acid were used as solublizing agents for plasminogen in electrophoretic experiments, only one broad band of the proenzyme was obtained on acetate cellulose, in starch block, and in acrylamide gel. In starch gel electrophoresis, however, both forms of plasminogen – the native or euglobulin and Kline’s or Pseudoglobulin plasminogen – separated into six bands. These migrated toward the cathode at room temperature in borate or veronal buffer in the alkaline range and showed full activity in fibrinagar-streptokinase plates.

ABSTRACT The isozymic patterns of tyrosine aminotransferase, NADP malate dehydrogenase, NADP isocitrate dehydrogenase, and tetrazolium oxidase were examined by starch-gel electrophoresis in Tetrahymena pyriformis, syngen 1. The genetics of the alleles controlling these enzymes was studied through a breeding program. Each enzyme locus was shown to assort vegetatively, as do other loci in this organism. A detailed analysis of the assortment process for the tyrosine aminotransferase locus indicated that the rate of stabilization of heterozygotes into pure types was essentially identical to previously-reported rates for other loci.

By varying conditions of starch gel electrophoresis, factors contributing to the resolution of myogen proteins from chicken breast muscle have been studied. Variables examined included composition of the myogen extractant, protein concentration, ionic strength of electrophoretic media, pH of gel media, plane and direction of electrophoresis, and the nature of cations and anions in gel media and bridge solutions. The significance of anions was more closely studied with constant buffer systems, and gradient systems in which bridge electrolyte differed from, and gradually altered, the gel medium. Optimal separation was obtained in gradient systems with 0.10 M sodium chloride bridge solutions, and gel media of sodium cacodylate, pH 6.9, μ 0.010, which resolved 12 cationic zones, and sodium veronal, pH 7.4, μ 0.010, which resolved 10 anionic zones. These buffers in two-dimensional sequence revealed a total of about 24 components in this myogen.
