Role of sulfhydryl groups of proteins in the reaction of early avian embryos to thermal effects (Russian)

Differences in the character of reaction of early embryos to hypothermia and β mercaptoethanol and absence of the protecting influence of cystein during exposure to cold lead to the conclusion that sulfhydryl protein groups are not of great significance in reactions of early avian embryos to hypothermal effects. Participation of these protein groups may be supposed in the reaction of early gastrulation stages under exposure to high temperature.
