Although there are a large number of protocols for the isolation of small quantities of plasmid DNA from bacterial cells (minipreps), this unit presents four procedures based on their speed and success: the alkaline lysis prep, a modification of the alkaline lysis prep that is performed in 1.5-ml tubes or 96-well microtiter dishes, the boiling method, and a lithium-based procedure. A support protocol provides information on storing plasmid DNA.
