DNA Sequencing GelsBuffers and gel solutionsLong Ranger: we started using this in early 1995. Great stuff; the best thing is that the gels are not sticky after drying, even without removal of the urea. Long Ranger Gel Solution is available from many scientific supply companies and is a JT Baker reagent, cat # 4730-02 (50% concentrate).The table below is used by our lab, and is sufficient for a standard 35 x 43 cm x 0......阅读全文

二代测序（Next－generation－sequencing）的定义
二代测序也被成为高通量测序指的是现代不同的测序技术，不同于之前的Sanger测序，它的速度更快，价格也更为便宜，主要有以下几个平台： － Illumina (Solexa) sequencing － Roche 454 sequencing － Ion torrent: Proton
二代测序（Next－generation－sequencing）的原理
此处主要介绍Illumina 平台的工作原理。 从本质上而言，二代测序（NGS）和Sanger测序相同，都是在每一个测序周期中，利用计算机检测DNA聚合酶催化荧光标记的dNTP结合到DNA模板时产生的荧光信号。但与Sanger单位时间检测单片段不同的是，NGS能同时检测成千上万的孔道的信号，因

单细胞测序技术(single－cell－sequencing)－综述（一）
单细胞生物学最近几年是非常热门的研究方向。在这一领域中，最前沿的则是单细胞测序技术。传统测序方法一次处理成千上万个细胞，得到的变异水平也是成千上万个细胞的平均后水平。但是，就如同世界上没有完全相同的两片树叶一样，没有两个细胞是完全相同的。所以，单细胞测序对于研究单个细胞就显得至关重要。单细胞测序可以
