Earlier studies with paper and starch gel electrophoresis of plasma from birds with erythroblastosis indicated an alteration in the mobility of one of its protein components. This protein has now been shown to be α-lipoprotein. Efforts have been made to simulate leukemic changes experimentally in normal plasma. Of all the treatments and materials tried, only incubation with turpentine and pinene compounds produced alterations in the electrophoretic pattern closely resembling those in leukemia.

Electrophoresis Of Proteins

An improved apparatus and procedures for starch-gel electrophoresis of proteins of wheat flour are described; highly reproducible separation of the protein components was achieved. By starch-gel electrophoresis it was shown that similar protein components occur in the extracts of wheat flour obtained with a variety of solvents; however, there were marked differences in the proportions of these components in various extracts. Several protein components were present in the fJ'actions separated by ion-exchange chromatography of' the proteins soluble in Bodium pyrophosphate and of those soluble in acetic acid; some fractions containeda number of similar protein components.

Species Specific

The species specific muscle myogens of Salmo gairdnerii, Oncorhynchus masou, O. masou ishikawae, O. kisutch, O. tshawytscha, O. keta, O. nerka, and O. gorbuscha are compared by starch gel electrophoresis. Plasma proteins of these same species are also examined by polyacrylamide disc electrophoresis. The range of usefulness of muscle myogens in species identification, and equally significantly, their value in establishing phylogenetic relationships of closely related groups, as the genus Oncorhynchus, are discussed. The myogen patterns of O. keta and O. gorbuscha from the Asiatic and North American coasts were found to be identical, further supporting the concept of absolute species specificity of these patterns.

Alterations of the plasma proteins have been previously demonstrated in avian erythroblastosis by paper and now by starch gel electrophoresis. With the latter technique, eight protein zones are recognized in normal plasmas. Heparin contributes an additional non-staining zone. In leukemic plasmas two more zones occur while another zone shows significant retardation.Heparin is not responsible for these changes because they are also observed in oxalated plasmas, but there is evidence of increased binding of heparin in leukemic plasma.

Polyacrylamide disc electrophoresis of plasma proteins and starch-gel electrophoresis of hemoglobins and muscle myogens of adult and ammocoete forms of three species of Great Lakes lamprey were carried out. Blood proteins were shown to undergo marked changes upon transformation of the ammocoete into the adult form. Muscle myogen did not undergo any change during transformation. The muscle myogen electropherograms of Ichthyomyzon unicuspis and Lampetra lamottei were found to be the same.

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.

Procedures are described for separation and purification of electron-dense bodies previously observed in intact endosperm by electron microscopy. Isolated bodies consist largely of protein. By starch-gel electrophoresis, the bodies contain predominantly slow-moving protein components similf1l' to those found in acetic acid extracts of whole endosperm.

1. The plasma proteins of six inbred strains of mice have been studied, using starch-gel electrophoresis.2. The existence of two alternative plasma transferrin (β-globulin) phenotypes has been demonstrated. Five of the strains have one of these and one strain has the other. Each of the two transferrin patterns comprises three (or possibly only two) electrophoretic bands. The two patterns differ in all of these bands.3. The two transferrin types recognized are determined by a pair of allelic, autosomal genes (designated TrfA and TrfB). The TrfA phenotype (CBA strain) is determined by the genotype TrfA/TrfA, and the TrfB phenotype (A, C57BL, JU, KL, RIII strains) by the genotype TrfB/TrfB. The phenotype TrfAB, of the heterozygote (genotype TrfA/TrfB), is distinguishable and shows four (or possibly only three) bands. In this way it closely resembles a mixture of equal parts of TrfA and TrfB plasma.4. No linkage was detected between the Trf locus and sex, the agouti locus or the haemoglobin locus.5. The possible molecular basis of the action of the transferrin alleles in the mouse, and the widespread distribution in mammals of polymorphism involving the transferrins, are discussed.

SummaryThe hemoglobin pattern of 18 inbred strains of mice was studied by starch-gel electrophoresis. In 7 strains (C57BL/10, C57BL/6, C57BR/cd, C57L, C58, SWR, and SEC/1Re) the electrophoretic pattern was found to be of single-band type: in the remaining 11 strains (AKR, DBA/1, DBA/2, CBA, C3H/He, C3HeB/Fe, Fl/1Re, RF, 129, A, and A/He), 6 components were constantly observed when the electrophoretic run was carried out for 20 hours. Hemoglobin from late C57BL/6 fetuses showed an electrophoretic pattern identical to that of the adult animal. Hemoglobin from AKR and DBA/2 late fetuses and newborns showed an electrophoretic pattern similar to that of the adult animal, but the slowest band was more intensely stained as compared with the corresponding band of the adult animal.

Plasma protein changes in avian erythroblastosis previously studied with paper and starch gel electrophoresis have now been examined with a two-dimensional technique combining the two methods. The differences affect chiefly one zone which migrates in the α-globulin region.
