基因克隆(gene－clone)的几种常用方法介绍1
基因(gene)是遗传物质的最基本单位,也是所有生命活动的基础。不论要揭示某个基因的功能,还是要改变某个基因的功能,都必须首先将所要研究的基因克隆出来。特定基因的克隆是整个基因工程或分子生物学的起点。本文就基因克隆的几种常用方法介绍如下。1 根据已知序列克隆基因对已知序列的基因克隆是基因克隆方法中最
基因克隆(gene－clone)的几种常用方法介绍2
其基本原理是：用一个在种源上相近的基因组将靶基因组中所有共同的基因掩盖起来,而只暴露出特异的基因,在整个反应中只有特异基因能被扩增。其操作程序为:(1)用同一限制性内切酶(一般用Bam HI,Bgl II或Hind III)同时处理靶基因组和掩盖基因组DNA，其中掩盖基因组DNA的量至少要2

转染，so－easy!－再也不用担心！
转染可谓是做生物学实验的大家经常会考虑的一项实验技术，大致原理也都是明白的。实验室的师妹也一直在进行这个实验，最近她却一直愁眉苦脸，问了才知道，原来她转染完的细胞，去跑qpcr验证的结果一直不行，转染效率太低以至于无法进行后续的实验。到底转染是什么呢，为什么转染效率不高呢，今天我们就来一起讨论一
