SummaryPolymorphic prealbumins (Pa A, Pa AB and Pa B) from hen's egg yolk (Gallus gallusL.) were isolated by gel filtration. Prealbumin was homogeneous on immunoelectro‐phoresis, gel filtration, and ion‐exchange chromatography, but heterogeneous on starch gel electrophoresis (five bands). The heterogeneity could be removed by neuraminidase treatment. Some physical and chemical properties were determined, namely molecular weight (19,500), N‐terminal amino acid (aspartic acid), isoelectric point (pH 4.6‐4.7), A1%1cm,280nmvalue (18.5), absorption spectrum, solubility at different conditions, and the effect of heating. Amino acid composition was estimated too, and the presence of about 4% hexose was

摘要:

SummaryThe effect of the red cell antibody, anti‐Ea, on the red cells of piglets in four litters was studied. Although the antibody was absorbed from the colostrum by all the piglets, it had little effect on their packed cell volume, haemoglobin and red cell counts, and no differences were noted between Ea‐positive and Ea‐negative piglets in the same litter, despite the fact that red cells of the former were positive for the direct Coomb's test for up to a week after birth.Anti‐Ea was not detected in the serum of Ea‐positive piglets, all of it apparently being taken up by their red cells, unlike the Ea‐negative ones, in whose serum anti‐Ea could be detected for up to fifteen

SummaryElectrophoretic investigations of the protein and enzyme groups of 8 plasma and of 11 red cell systems have been carried out on 42 samples of seals of the speciesMirounga leonina(L.) from Macquarie Island.Variation was demonstrated in the following 5 systems: phosphoglucomutase, red cell acid phosphatase, phosphohexose isomerase, albumin and pre‐albumi

SummaryElectrophoretic variation in red blood cell tetrazolium oxidase has been detected in a laboratory colony of the fat‐tailed dunnart,Sminthopsis crassicaudata.Evidence from family data suggest that this variation is determined by a pair of co‐dominant autosomal alleles,ToAandToB, heterozygotes possessing enzymatically active hybrid prot

摘要:

SummaryBy a variety of electrophoretic procedures it has been found thatGallus gallus, whether as jungle fowl or as chickens, differs consistently from Sonnerat's jungle fowl,G. sonnerati, in three egg white proteins: G3ovoglobulin, G2ovoglobulin and glutamyl peptidase. The electrophoretic patterns of egg white hybrids betweenG. gallusandG. sonneratiare identical to those obtained after simpiy mixing the egg whites; there is no evidence for hybrid protein zones. Although Japanese data on serum amylase can be interpreted as indicating introgressive hybridization in the origin of the domestic fowl, so far the egg protein data are negative in this respect.

摘要:

SummarySix phenotypes of aspartate aminotransferase (AAT) and three phenotypes of adductor muscle protein were found in extracts of the native oyster (Ostrea lurida) by starch gel electrophoresis. The AAT phenotypes were presumed to be genetic variants under the control of three allelic genes (A, B, C) and the muscle protein phenotypes under the control of a two‐allele system (AandB

摘要:

SummaryPolymorphism of phosphoglucomutase (PGM) in horse erythrocytes was studied by means of starch gel electrophoresis.Three different phenotypes, F, FS and S, were found. Family data supported the genetic theory of two autosomal, codominant allelesPGMFandPGMScontrolling the variation.The gene frequencies were estimated to 0.28 and 0.72, respectively, in the North‐Swedish Horse breed and to 0.13 and 0.87, respectively, in the Swedish Trotter Breed.The probabilities of excluding a falsely assigned stallion in the PGM system were calculated to 0.16 and 0.10, respectively, in the two breed
