An Electrophoretic Study of the Proteins of Egg White

Abstract

Vol. 62 catalytic thermal decomposition of (a) ethylene for the hydrogenation of acetone at 110°, (b) methane for the hydrogenation of carbon dioxide at 315°, and of nitrous oxide at 73.5°2. The experimental evidence indicates that the surface of the nickel catalysts studied was non-uniform because (a) catalysts which no longer catalyzed the decomposition reactions were still active at lower temperatures in the hydrogenation reactions, (b) certain parts of the surface were more active than others in the hydrogenation of acetone, (c) heating in hydrogen a surface upon which the hydrogenation of nitrous oxide had occurred caused selective activation or poisoning according to conditions, (d) the nickel surface responsible for about two-thirds of the hydrogenation of carbon dioxide could be poisoned without affecting the nickel surface which catalyzed the hydrogenation of nitrous oxide.

Immunological Studies of Insect Metamorphosis

“…Antiserum-agar tests of electrophoretic fractions indicate that, at pH 7.7, antigen 7 is associated with the female characteristic electrophoretic component, and probably to some extent with the more slowly moving major component. The association of antigen 7 with more than one electrophoretic component is probably attributable to protein-protein interactions of the sort which have been observed previously in complex protein solutions (6). Such interactions, by affecting the mobility of one or more protein, could also account for the fact that the fast component, while appearing as a single peak in the female pattern at pH 7.7, can be resolved into two peaks in the male pattern.…”

A century of poultry genetics

“…The examples of egg white proteins and blood group B illustrate the pathway from biochemical genetics to molecular genetics before entering the era of gene mapping and finally whole-genome sequencing. Egg white proteins were initially characterized by their electrophoretic properties, with a pioneer study by Longsworth et al (1940) followed by Forsythe and Foster (1950). Baker and Manwell (1962) were the first to use the terminology of 'Molecular genetics of avian proteins' and showed genetic variation at three loci: albumin A3 with quantitative variation due to a null allele, and globulins G2 and G3, showing qualitative variation with two alleles each.…”
