Extraction and Purification of Plasmid DNA
Time of Update: 2021-03-05
Plasmids may be isolated by a variety of methods many of which rely on the differential denaturation and reannealing of plasmid DNA compared to chromosomal DNA. Many of these are rapid, small-scale “minipreps” that may be used effectively for plasmid analysis and further manipulation. The methods differ primarily in the means by which cells are lysed.
