title: Amylase activity increases in the yolk of fertilized eggs during incubation in chickens.
abstract: Amylase activity was detected in the egg of chickens. In unfertilized eggs, no change of amylase activity was observed during 22 days incubation, however, in fertilized eggs, amylase activity increased markedly during embryonic development. The increase depended upon an increase of amylase in the yolk, not in the albumen. Isoamylases in the yolk were electrophoretically identical to those in the pancreas of the embryo or the hen.
