Western blot analyses of yolk proteins of the White Leghorn hens showed that an ovalbumin-like molecule was included in day 16 eggs but not in the ovarian follicles, and very little in newly deposited eggs. Northern hybridization, as well as in vitro translation, of poly(A)+ RNAs prepared from the yolk sac membranes of developing embryos gave no signal for ovalbumin messages. These results imply that the present ovalbumin-like protein of yolk has its origin in egg white, not being a de novo synthesis product in the yolk sac membranes.
