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.

Examination of 17 presumptive gene loci by starch-gel electrophoresis revealed differential mobilities only at acid phosphatase-1, alcohol dehydrogenase, esterase-1, and phosphoglucomutase between Nocomis biguttatus and N. micropogon. No intraspecific variation was observed for any loci. The genetic identity (I) and genetic distance (D) were 0.874 and 0.134, respectively. The correlation of electrophoretic mobilities and nuptial tubercle pattern in sexually dimorphic males supports the present taxonomic distinction of these species and provides a simple, unambiguous means of identifying any individuals.Stepwise discriminant function analysis of a series of mensural characters was used to compare fish identified as to species by electrophoresis. At best this correctly assigned fish to their respective species in 85.7% of cases, with a probability of misclassification of 0.1335.This study suggests these two are sibling species, based on a comparison of biochemical and morphological differentiation.

Histories extracted from various organs of the rat have been fractionated by electrophoresis on Polyacrylamide gels. The most convenient reagents to form the gel were selected and the effects of varying concentrations of these reagents on the resolution of histones were investigated. Optimum conditions for the separation of histones were found to be the same as those for starch gel electrophoresis. More consistent results were obtained with the use of Polyacrylamide gels because these gels were equilibrated to constant pH and ionic strength prior to electrophoresis and the gels were electrophoretically destained to demonstrate the histone bands.
