摘要: 建立起适于临床应用的抗DNA抗体化学发光酶联免疫分析法。该法精密度良好,相对标准偏差为2.4%.比ELISA法更加简便、经济、省时,同时提高了灵敏度(8倍)和血清的阳性检出率。探讨了检测系统中对碘苯酚增强鲁米诺-过氧化氢-辣根过氧化物酶化学发光反应机理。

Abstract: Amethod for determination of the DNAantibody in serum was established based on chemiluminescence enzyme-linked immunosorbant assay(CL-ELISA).The DNAantigen is immobilized on the inner surface of polystyrene cup, then reacts with DNAantibody in serum sample, only specific antibody binds to antigen to form Ag-Ab HRPlabeled anti-HuIgGreacts with DNAantibody molecules in the complex to form second Ag-Ab, finally determine the label with p-IPenhanced luminol-H2O2-HRPchemiluminescence system.The clinical applications show that present method has a good correlation with ELISA.The correlation coefficient is 0.958.It is more sensitive, convenient and economical than ELISA.
