  • Title: Heteroimmunization with isolated human ova.
    Author: Takai I, Mori T, Noda Y, Nishimura T.
    Journal: J Reprod Fertil; 1981 Jan; 61(1):19-24. PubMed ID: 7005437.
    Abstract:
    Rabbit antiserum raised against isolated human ova produced an intense immunofluorescence and a precipitate on the outer surface of human and porcine zonae pellucidae. The antiserum reacted with none of 22 human tissues nor with any of 4 body fluid components by immunofluorescence or immunodiffusion analysis, but the antiserum agglutinated AB erythrocytes after absorption with O erythrocytes. The anti-zona activity was achieved by higher titres for human than for porcine zonae. Immunofluorescence on porcine zonae was completely abolished by absorption with porcine ova, whereas a weak but definite fluorescence remained on human zonae. These findings indicate that the human zona pellucida consists of at least three distinct components; (1) a specific antigen(s) shared by human and porcine zonae, (2) an antigen(s) specific to human zonae, and (3) a non-specific antigen(s) associated with the blood group substances.
