Levels of serum protease inhibitors during fetal and postnatal development of the pig
Using electroimmunoassay the levels of the individual protease inhibitors, α2-macroglobulin f, α2-macroglobulin s, inter-α-trypsin inhibitor, α1-protease inhibitor and α2-antitrypsin were studied in the serum and the amniotic fluid during the fetal and postnatal development of the pig. High concentrations, far above the adult ones, of α2-antitrypsin and especially α1-protease inhibitor, were obser
