Abstract

A solid-phase radioimmunoassay for the rapid determination of human immunoglobulin M (IgM) rheumatoid factor (RF) has been developed. Preparation of the solid phase for the assay involved the formation of complexes between respiratory syncytial virus-specific human IgG antibodies and virus antigen on the surface of polystyrene balls. Binding of serum RF to IgG in the immune complex was subsequently detected by 125I-labeled mu-chain-specific antibodies to human IgM. The amount of radioactive indicator antibody bound was converted to units of RF by comparison to the standard curve for an RF reference-serum pool. This assay should prove useful in studies of the physiological role of RF, since it can effectively measure low levels of circulating RF.

摘要

已开发出一种用于快速测定人免疫球蛋白M(IgM)类风湿因子(RF)的固相放射免疫测定法。该测定法的固相制备涉及呼吸道合胞病毒特异性人IgG抗体与聚苯乙烯球表面病毒抗原之间形成复合物。随后通过125I标记的人IgMμ链特异性抗体检测血清RF与免疫复合物中IgG的结合。通过与RF参考血清库的标准曲线比较,将结合的放射性指示抗体量换算为RF单位。该测定法在RF生理作用的研究中应会证明有用,因为它能有效测量循环中低水平的RF。
