Abstract

A rapid and easy final purification method is described for the isolation of plasmids from B. fragilis. Using RbTCA density gradient centrifugation in an airfuge ultracentrifuge ccc plasmid DNA can be separated from RNA, residual chromosomal DNA, linear and oc plasmid DNA. Pure ccc plasmid DNA is obtained from cultures of between 1 ml and 2 l in less than one day.

摘要

本文描述了一种从脆弱拟杆菌中分离质粒的快速简便的最终纯化方法。在空气离心机中使用RbTCA密度梯度离心,可将ccc质粒DNA与RNA、残留的染色体DNA、线性和开环质粒DNA分离。在不到一天的时间内,可从1毫升至2升的培养物中获得纯ccc质粒DNA。
