摘要:A material that strongly reacts with antibodies against alpha1-antitrypsin, but has little trypsin inhibitory capacity, has been isolated and purified to homogeneity from human liver. The molecular weight of the crossreacting material is about 18,000, which is significantly lower than that of serum alpha1-antitrypsin. The material isolated from the liver of a homozygous variant subject (ZZ) with alpha1-antitrypsin deficiency is readily distinguished by electrophoresis from the material extracted from a normal (MM) subject. The tissues from a heterozygous variant subject (MZ) contain the two components. The immunologically crossreacting material is presumably synthesized by the gene that codes for alpha1-antitrypsin.
