Abstract

The mol. wt and charge characteristics of Gm(1) antibodies from normal human serum were studied by gel filtration and DEAE- anion exchange chromatography. The effect on anti-Gm(1) activity, of incubating individual antisera with disulphide reducing agents, and with anti-IgG or anti-IgM immunoabsorbents were also studied. The results demonstrate the existence of a low molecular weight IgM protein with anti-Gm(1) activity.

摘要

通过凝胶过滤和DEAE-阴离子交换色谱法研究了正常人血清中Gm(1)抗体的分子量和电荷特性。还研究了用二硫键还原剂、抗IgG或抗IgM免疫吸附剂孵育个体抗血清对抗Gm(1)活性的影响。结果表明存在一种具有抗Gm(1)活性的低分子量IgM蛋白。
