Southern 杂交是分子生物学的经典实验方法。其基本原理是将待检测的DNA样品固定在固相载体上，与标记的核酸探针进行杂交，在与探针有同源序列的固相DNA的位置上显示出杂交信号。通过Southern杂交可以判断被检测的DNA样品中是否有与探针同源的片段以及该片段的长度。该项技术广泛被应用在遗传病检测、DNA指纹分析和PCR产物判断等研究中。但由于该技术的操作比较烦琐、费时，所以现在有一些其他的 ...

第一节 概 述 　　质粒具有稳定可靠和操作简便的优点。如果要克隆较小的DNA片段(＜10kb)且结构简单质粒要比其它任何载体都要好。在质粒载体上进行克隆从原理上说是很简单的，先用限制性内切酶切割质粒DNA和目的DNA片段 然后体外使两者相连接 再用所得到重组质粒转化细菌即可完成。但在实际工作中 如何区分插入有外源DNA的重组质粒和无插入而自身环化的载体分子是较为困难的。通过调整连接反应中外源DNA ...

来自上海某研究所的某博士的研究课题是寻找导致某种疾病的相关基因，最近他获得了这一疾病的微卫星家族标记图谱，但是这种串联重复的微卫星位点并不能完全满足他的分析要求，因此他决定转向作单核苷酸多态性SNPs（single nucleotide polymorphism，发音为“snips”）基因分型。确实，如果你的研究课题也是寻找易感基因，那么SNPs是一种比较而言可行而且高效的方法，这主要是因为它有几 ...
