  论文目的:建立血清抗Ⅱ型胶原蛋白抗体的ELISA检测法,观察其在类风湿性关节炎患者中的初步应用.论文方法:以Ⅱ型胶原蛋白(collagen typeⅡ,CⅡ)作为包被抗原,优化实验条件,建立血清抗Ⅱ型胶原蛋白抗体ELISA法.对120例RA病人和100例健康人血清抗Ⅱ型胶原蛋白抗体进行检测.论文结果:血清抗Ⅱ型胶原蛋白抗体ELISA法条件为:用PH7.6 0.05 mol/L磷酸盐缓冲液将CⅡ配成20μg/ml,4℃12h进行包被,继以10%胎牛血清、37℃2h为封闭条件;用含10%胎牛血清的缓冲液分别将血清作1∶50稀释、酶标抗体作1∶5000稀释;采用波长450nm进行测定.采用建立的ELISA法,发现RA患者和健康人血清抗Ⅱ型胶原蛋白抗体阳性率分别为20.83%和2%,两组有明显的统计学差异(P<0.01).
