Characterization of a new alpha-glycoprotein as the major serum component in later fetal and newborn pigs.
1. Using crossed immunoelectrophoresis, fetuin, alpha-fetoprotein, albumin, transferrin, alpha1-antitrypsin and a fetospecific-like alpha-glycoprotein, were identified as the main serum components in fetal pig (Sus scrofa domesticus). 2. Fetuin was found to be a trypsin inhibitor, but not a chymotrypsin inhibitor. 3. The fetospecific-like alpha-glycoprotein, not previously reported, accounted for 50% of the total serum proteins in newborn pigs. This protein, however, was a minor component of the adult serum.
