摘要: 采用胶体金标记鼠抗人IgM μ链抗体,肺炎支原体P1抗原作包被蛋白,检测肺炎支原体特异性抗体IgM.经对免疫金制备条件进行优化,制备了胶体金免疫层析检测试纸条.将该试纸条与市售试剂盒作对比检测,总符合率为99.17%,表明本方法灵敏度较高、特异性较强,价格低,操作简便快捷,更适合MP感染患者早期临床筛查.Abstract: Using colloidal gold-labeled mouse anti-human IgM μ chain antibody,Mycoplasma pneumoniae P1 protein antigen for coating,immuno-gold preparation conditions were optimized to prepare colloidal gold immunochromatographic test strip.The test strip kit was contrasted with that in market,total coincidence rate was 99.17%.The results showed that the test strip had high sensitivity,specificity,low price.It was more suitable for MP infection in early clinical screening,and was easy and quick to operate.
