NOWEDGESequencingGels
I have been using an alternative to wedge gels that saves acrylamide, cuts gel drying time to 20 min and gives as good or better band squashing at the bottom of the gel. It was published in BioTechniques about 3 or 4 years ago (email me if you want the reference).The method goes as such:Run the gel with 0.5X TBE in the top tank and normal 1 X TBE in the bottom tank. Just after the last (or in the case of one load - t......阅读全文

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
