DNA storage is an important aspect of DNA extraction projects as it ensures the integrity and stability of the extracted DNA for downstream applications. [ 15 ] One common method of DNA storage is ethanol precipitation, which involves adding ethanol and a salt, such as sodium chloride or potassium acetate, to the extracted DNA to precipitate it ...
Alkaline lysis is the process of isolating plasmid deoxyribonucleic acid (DNA) in bacteria. It is a standard method used in molecular biology to isolate the plasmid without obtaining chromosomal DNA. The first alkaline lysis was performed by Birnom and Doly in 1979. [1]
A plasmid preparation is a method of DNA extraction and purification for plasmid DNA. It is an important step in many molecular biology experiments and is essential for the successful use of plasmids in research and biotechnology. [1] [2] Many methods have been developed to purify plasmid DNA from bacteria.
There are several methods to isolate plasmid DNA from bacteria, ranging from the plasmid extraction kits (miniprep to the maxiprep or bulkprep), alkaline lysis, enzymatic lysis, and mechanical lysis . [33] The former can be used to quickly find out whether the plasmid is correct in any of several bacterial clones.
The different stages of the method are lyse, bind, wash, and elute. [1] [2] More specifically, this entails the lysis of target cells to release nucleic acids, selective binding of nucleic acid to a silica membrane, washing away particulates and inhibitors that are not bound to the silica membrane, and elution of the nucleic acid, with the end result being purified nucleic acid in an aqueous ...

Since DNA is a very hydrophilic molecule, it often cannot penetrate through the bacterial cell membrane. Therefore, it is necessary to make bacteria competent in order to internalize DNA. This may be accomplished by suspending bacteria in a solution with a high calcium concentration, which creates tiny holes in the bacterium's cells [citation ...
This method is one of the most widespread [6] [7] methods for isolating nucleic acids from biological samples and is known as a simple, rapid, and reliable [2] method for the small-scale purification of nucleic acid from biological sample. This method is said to have been developed and invented by Willem R. Boom et al. around 1990.
