Abstract

The distribution of the five plasma proteins that are quantitatively most important during development in the sheep has been studied in embryos of 15 to 21 days gestation. The three primary embryonic layers and tissues that differentiate from them were tested for the presence of alpha-fetoprotein (AFP), fetuin, albumin, transferrin and alpha 1-antitrypsin using the indirect immunoperoxidase method. Fetuin was the most prominent of these proteins particularly in the developing central nervous system. Fetuin and transferrin appeared early in the differentiating mesoderm and, with albumin and AFP, were detected in tissues originating from all three layers during the course of development. alpha..
