Urine from some patients, when concentrated approximately three hundred fold and immunoelectrophoresed against anti-IgG, shows an unexpected additional precipitin line in the alpha-globulin region. This reaction has been shown to be due to the presence of a low molecular weight (approximately 20 000) fragment of the heavy chain of IgG. A retrospective examination of immunoelectrophoretic plates run over a period of five years has revealed that this fragment was present in 30 out of 110 patients.
一些患者的尿液在浓缩约300倍后，与抗IgG进行免疫电泳时，在α球蛋白区域显示出一条意外的额外沉淀线。已证明这种反应是由于存在低分子量（约20000）的IgG重链片段。对五年期间进行的免疫电泳板的回顾性检查发现，110名患者中有30名存在这种片段。
