DenaturingAgaroseGelElectrophoresisofRNA

The overall quality of an RNA preparation may be assessed by electrophoresis on a denaturing agarose gel; this will also give some information about RNA yield. A denaturing gel system is suggested because most RNA forms extensive secondary structure via intramolecular base pairing, and this prevents it from migrating strictly according to its size. Be sure to include a positive control RNA on the gel so that unusual ......阅读全文

凝胶电泳的实验原理

凝胶电泳(英语:Gel electrophoresis)或称胶体电泳 是一大类技术,被科学工作者用于分离不同物理性质(如大小、形状、等电点等)的分子。凝胶电泳通常用于分析用途,但也可以作为制备技术,在采用某些方法(如质谱(MS)、聚合酶链式反应(PCR)、克隆技术、DNA测序或者免疫印迹)检测之前部
