High anti-staphylolysin activity was found in the serum from a patient with multiple myeloma. The activity was confined to the monoclonal IgA protein and was dependent on an intact Fc part of the molecule. An Fc-dependent interaction with protein A was also demonstrated. In addition, a part of the monoclonal IgA was found to be complexed with alpha2-macroglobulin. The results imply an unusual Fc-reactivity of the IgA protein.
在一名多发性骨髓瘤患者的血清中发现了高抗葡萄球菌溶血素活性。该活性局限于单克隆IgA蛋白,并且依赖于分子完整的Fc部分。还证实了与蛋白A的Fc依赖性相互作用。此外,发现一部分单克隆IgA与α2-巨球蛋白复合。结果表明IgA蛋白具有异常的Fc反应性。
