Circulating immune complexes were isolated from the serum of patients with AIDS, as well as patients with other acute and chronic viral diseases. Analysis of these immune complexes by methods of flow cytometry and by radioimmune (Raji cell) assay revealed a prevalence of IgA complexes in the serum of AIDS patients and a prevalence of IgG complexes in the serum of patients with other viral diseases. Raji cells bind immune complexes via Fc and complement (C3) receptors and may detect IgA immune complexes more efficiently than a C1q assay since IgA has no affinity for C1q.
从艾滋病患者以及其他急慢性病毒性疾病患者的血清中分离出循环免疫复合物。通过流式细胞术和放射免疫（拉吉细胞）测定法对这些免疫复合物进行分析，结果显示艾滋病患者血清中以IgA复合物为主，而其他病毒性疾病患者血清中以IgG复合物为主。拉吉细胞通过Fc和补体（C3）受体结合免疫复合物，并且由于IgA对C1q没有亲和力，所以它可能比C1q测定法更有效地检测IgA免疫复合物。
