7年分子克隆经验总结
做了快7年的分子克隆,从加样加不好,到现在轻松PCR,我想分子生物学这块还是有很多经验可以分享一下的。或许很多人会说分子克隆过程中出现问题最多的大概就是连接了,大家抱怨的也最多,我也陷入在个步骤上很久。经过长时间的摸索我在连接这个问题上有一些体会,我认为连接的问题多集中在连接的体系、DNA的用量、v

基因载体的相关介绍
基因载体本身是DNA,除根据其来源分为质粒载体、噬菌体载体、病毒载体等外,还可以根据它们的主要用途分为克隆载体与表达载体。根据它们的性质分为温度敏感型载体(temperature sensitive vector)、融合型表达载体、非融合型表达载等。 基因载体(vector) 的作用是运载目的

病毒介导基因转移
病毒介导基因转移:前述的化学和物理方法都是通过传染方式基因转移。病毒介导基因转移(viral mediatedgene transfer)是通过转换方式完成基因转移,即以病毒为载体(vector),将外源目的基因通过基因重组技术,将其组装于病毒上,让这种重组病毒去感染受体宿主细胞,这种病毒称为病毒运

Gateway的原理
Gateway也可以被视为一种克隆操作平台:把目的基因克隆到入门载体(Entry Vector)后,就不用依赖限制性内切酶,而靠载体上存在的特定重组位点和重组酶,高效、快速地将目的基因克隆到其它的受体载体(Destination Vector,目的载体)上。Gateway的原理也是建立在噬菌体DNA
