【摘要】 在研究影响本法准确性的各种因素后,确定了各种试剂和抗血清等的浓度以及操作步骤。共测定1205例正常人血清,150例脐带血和61例病人脑脊液中IgD含量,与环状免疫单扩散法的结果甚为一致。本法比后法灵被度高约3000倍,与放射免疫法的灵敏度相似,可测出脑脊液中微量的IgD。本法操作简单,无需特殊设备及防护。

【Abstract】 An innovation of double antibody sandwich enzyme immunoassay for the determination of human IgD was reported. Optimal conditions for best results were investigated. Results suggested that this method was as reliable as the classical Mancini radial immunodiffusion method and the sensitivity of the former was approximately 3,000 times higher than that of the latter: i.e., even an amount of 1.5ng/ml of IgD could be detected. This assay might be used for the determination of human IgD in adult or cord sera and cerebro-spinal fluid ( 1,700, 150 and 61 samples ) and was much simpler and faster than radioimmunoassay and required no special protection.
