Starch-gel electrophoresis was used to demonstrate two forms of glutathione S-transferase in human erythrocytes. Whereas considerable inter-individual differences in enzyme activity and electrophoretic patterns were detected, intra-individual differences were small.

AbstractTwelve enzymes (encoded by 14 loci) in liver flukes of Fasciola species originating from Japan (parthenogenetic triploids), Korea (parthenogenetic diploids), the United States of America (USA) and Australia (all sexual diploids) were analysed using starch gel electrophoresis. Variation in electrophoretic patterns between samples was detected at five enzyme loci (Ak, Got, Gpi, 6-Pgd and Pgm-2). Japanese worms (31, of which six were established as uniparental laboratory strains), which reproduce by parthenogenesis, exhibited three different isozyme patterns. This indicates that triploidy has arisen more than once in Japanese flukes. Japanese Fasciola sp. can be separated into three types on morphological grounds. For the six laboratory strains of Japanese worms, the parental morphological type was known. Each of the three isozyme patterns observed was restricted to one morphological type. Most alleles detected in the Japanese triploids were also found in diploid worms from the other countries: the only alleles not represented elsewhere were four at the Got locus and two at the Pgm locus. Flukes from a laboratory strain derived from a single Korean diploid worm resembled the Japanese worms in genotype more closely than did American (seven uniparental laboratory strains) or Australian (30 worms) specimens. Worms from the last two countries were closely related.

This paper describes a Negro family with congenital nonspherocytic hemolytic anemia associated with glucose-6-phosphate dehydrogenase deficiency. All four affected males in this family showed a hemolytic anemia characterized by low hemoglobin, reticulocytosis, and jaundice. There was no detectable G-6-P D in the red cells and about a tenth of normal enzyme activity in the white cells. By starch gel electrophoresis, the G-6-P D was present as a single band which migrated at the rate of 104% of normal. Physico-chemical studies revealed a marked increase of the Michaelis constant for both G-6-P and TPN, a marked lability of the enzyme upon heating at 40°C and 48°C, and a single narrow peak at pH 9.0. Most of these features were similar to those seen in the Oklahoma I variant. Four of the females in the family were studied (two sisters, the mother, and a maternal aunt of the propositus); all showed a lesser degree of anemia and reticulocytosis but no jaundice, except in the mother. There was a decrease of haptoglobins and both the mother and one sister showed a decrease of erythrocyte survival time as measured by chromium-51. The female members had between 11 and 26% of normal G-6-P D activity in the red cells and between 35 and 63% of normal enzyme activity in the white cells. Starch gel electrophoresis in the mother and aunt showed a single band which migrated at 110% of normal with a trail at the position of the affected males. The presence of a milder degree of hemolysis in the heterozygous carriers of the gene for G-6-P D deficiency associated with congenital nonspherocytic hemolytic anemia provides further support for the Lyon hypothesis in man.

Paper and starch-gel electrophoresis of serum proteins of several species and subspecies of poisonous and nonpoisonous snakes of Iran have been investigated. The patterns obtained, especially by means of the starch-gel method, are characteristic for each species. Electrophoretic patterns of samples of serum from different individuals of the same species were very similar.

Starch gel electrophoresis is currently used in our laboratory for the study of the genetics and evolution of alfalfa (Medicago sativa L.) and related species. An account is given of this technique, and the staining of the gels for enzyme activity of peroxidases, leucine-aminopeptidases, esterases, and alcohol dehydrogenases.

Characteristic Zone

Histories were extracted at pH 1.7 from washed nuclei of chicken erythrocytes, spleen, liver, and testis and compared by starch-gel electrophoresis at pH 5.0, ionic strength 0.020. Spleen and liver histories displayed the most complex electrophoretic patterns with 18 zones each and differed only in relative proportions of certain zones. Erythrocyte histone contained a characteristic zone while lacking a group present in spleen and liver histones. Testis histone with only seven zones differed markedly from the other three. These results were consistent with chromatograms of erythrocyte, spleen, and liver histones on sodium IRC-50. The suggested correlation of tissue-specific histones with cell differentiation is discussed.

Hemolyzates from the blood of coho salmon (Oncorhynchus kisutch) at various stages of development were subjected to micro-starch-gel electrophoresis. Three distinct electrophoretic patterns composed of different combinations of 18 hemoglobin tetramers were observed. Embryonic and yolk-sac alevins possessed 1 cathodic and 12 anodic components while fry retained only 3 of the 12 anodic polymorphs. During smoltification, 4 new cathodic components appeared and 2 of the anodic and the cathodic components of alevin hemolyzates reappeared. This latter pattern was retained until the fish spawned and died. Attempts to induce changes in the pattern of development of these hemoglobins by exposing fry and pre-smolts to extreme variations in dissolved oxygen, temperature, and salinity were completely unsuccessful.

Gel electrophoresis is at present the best procedure for the analytical fractiona-tion of wheat gluten proteins. Procedures more suitable for preparative studies, such as gel ffitration and column chromatography, have provided only partial fractionation on the basis of gel electrophoresis (Graham 1963; Lee et al. 1963; Wright, Brown, and Bell 1964). Gel electrophoretic patterns of fractions resulting from the carboxymethyl cellulose (CMC) fractionation of Simmonds and Winzor (1961) have been published by Graham (1963) and by Lee et al. (1963). These results showed that each fraction was heterogeneous, with considerable overlapping of electrophoretic bands from neighbouring fractions, and that fractions eluted late in the chromatogram were contaminated because of tailing of earlier fractions. The modification of the Simmonds and Winzor procedure described below results in an improved fractionation of gluten proteins as judged by starch-gel electrophoresis.

A method for the preparation of purified plasma antithrombin and heparin-cofactor is described. The method involves adsorption by aluminium hydroxide, separation on a DEAE-cellulose column by means of a graded salt concentration, and vertical curtain electrophoresis. A 100-fold increase in the specific activity of antithrombin and a 30-fold increase in the specific activity of heparin-cofactor have been achieved. In spite of the increased purification, no separation of the two activities was achieved. When a highly purified fraction was subjected to starch-gel electrophoresis for 16–18 h and then eluted from the gel, there was significant loss of heparin-cofactor activity but not of antithrombin activity. The electrophoretic patterns of the recovered proteins were not altered.

Phenotypic Convergence

Starch gel electrophoresis was used to examine the generic separation of the sphaeriid clams Musculium and Sphaerium. Twenty-five loci from 13 enzyme systems were resolved. Major differences in electrophoretic patterns were observed, and these appear to support the generic separation of Musculium and Sphaerium. Sphaerium occidentale, considered to be intermediate in form between Musculium and Sphaerium, is more closely related (electrophoretically) to other spieces of Sphaerium than to Musculium. The phenotypic convergence of S. occidentale with Musculium and its genotypic divergence from other species of Sphaerium can be related to habitat characteristics of these forms.
