Univalent 3.5S antibody fragments obtained from 7S rabbit antibody specific for human group A red cells, have a very much smaller association constant in their reaction with human group A red cells than have 7S or 5S antibody. Univalent 5S recombinants have a similarly low association constant, whereas bivalent 5S recombinants have an association constant similar to that of 7S antibody. It is concluded that this supports the authors' hypothesis that rabbit anti-A 7S antibody is normally attached to red cells by both its specific antibody groups.
从对人A血型红细胞具有特异性的7S兔抗体获得的单价3.5S抗体片段,在与人A血型红细胞的反应中,其结合常数比7S或5S抗体小得多。单价5S重组体具有同样低的结合常数,而双价5S重组体的结合常数与7S抗体的相似。由此得出结论,这支持了作者的假说,即兔抗A 7S抗体通常通过其两个特异性抗体基团附着于红细胞。
