Antibodies to glomerular basement membrane (GBM) of the rat could be fractionated according to their avidity by elution from trypsin-digested GBM (bound to Sepharose) with increasing concentrations of KSCN. The percentage of kidney-fixing antibody in each fraction and the degree of proteinuria induced as determined 24 h after injection increased with the avidity of the antibody fraction when equal doses were administered.
大鼠肾小球基底膜(GBM)抗体可通过用浓度递增的硫氰酸钾从胰蛋白酶消化的GBM(结合到琼脂糖珠上)上洗脱,根据其亲和力进行分级分离。当给予等量剂量时,各分级分离物中肾脏固定抗体的百分比以及注射后24小时测定的蛋白尿程度随抗体分级分离物的亲和力增加而增加。
