title: Proteins in the amniotic and allantoic fluids of fetal pigs.
abstract: Seven proteins were identified in the amniotic and allantoic fluids of fetal pigs (Sus scrofa domesticus) using crossed immunoelectrophoresis: albumin, fetuin, transferrin, alpha-fetoprotein (AFP), alpha 1-acid glycoprotein, alpha 1-antitrypsin and alpha 2-macroglobulin. The total protein concentrations were determined by the method of Bradford and individual protein concentrations by radial immunodiffusion or rocket immunoelectrophoresis. Transferrin and fetuin were the major proteins in amniotic fluid during the second trimester of gestation and together with AFP and albumin accounted for the majority of the total protein in amniotic, but not allantoic fluid.
