OVERVIEW. The alkaline lysis method of plasmid isolation was originally developed by Brinboim and Doly (1979). In this procedure, bacteria containing the desired plasmid are harvested from liquid bacterial culture by centrifugation.
ISOLATION OF PLASMID DNA . Purpose: Isolation of Plasmid DNA from a microbial source. Principle: Plasmids are extra chromosomal DNA that replicate independently of the bacterial chromosome. They are normally covalently closed, circular, super-coiled molecules.
The protocol below is meant to describe the general procedure for purifying plasmid DNA from bacterial cultures. If you will be using a kit, follow the kit's instructions. If you want to perform plasmid purification without using a kit, you can find a protocol for kit-free plasmid mini-prep at the bottom of this page.
Aug 8, 2023 · This easy-to-perform protocol is free from phenol extraction, density gradient steps, and DNA binding columns, and yields high-quality plasmid DNA. The protocol opens an easy scale up to yield a large amount of high-quality plasmid DNA, useful for high-throughput downstream applications. Key features.
Aug 16, 2022 · Isolation of Plasmid DNA from overnight cultures in LB. This method is spin column-based and purifies up to 100 \(\mu g\) of ultra-pure endotoxin-free plasmid DNA in less than 15 minutes. The result is plasmid DNA suitable for transfection, restriction endonuclease digestion, bacterial transformation, PCR amplification, and DNA sequencing.
Sep 10, 2013 · Specific protocols for alkaline lysis differ from laboratory to laboratory, however they are all based on the same principal. The fi rst stage is to grow the selected bacterial
