上海交通大学妇产科学03级七年制课件三 diagnosis of pregnancy-滕银成。
摘要本文探讨应用孕妇血浆中游离DNA进行无创性产前性别诊断的可行性。用柱分离法提取73例孕妇血浆中DNA,用巢式PCR技术检测其胎儿SRY基因。 结果73位孕妇血浆DNA含量为0.0062~0.3399μg/μL。巢式PCR检测胎儿SRY基因的灵敏度为97.37%(37/38),假阴性率2.86%(1/35),特异度85.71%(30/35),假阳性率13.16%(5/38),总符合率91.78%...
摘要以孕8~26周孕妇外周血为材料,经过Percoll密度梯度离心初步富集,胎儿细胞特异性抗体—HbF标记、识别胎儿有核红细胞,母体和胎儿有核红细胞的精确区分是以胎儿和成人血红蛋白的组成差异为基础的。胎儿细胞胞浆黄染,而具有成人血红蛋白的母体细胞没有颜色。显微操作法获取全部阳性细胞后,以其全基因组扩增(PEP)的产物为模板,进行性别检测、DMD基因的多重PCR检测和STR连锁分析。结果,20名孕妇...
