  2. DNA extraction - Wikipedia

    en.wikipedia.org/wiki/DNA_extraction

    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 ...

  3. Alkaline lysis - Wikipedia

    en.wikipedia.org/wiki/Alkaline_lysis

    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 ]

    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 ...

  6. Plasmid preparation - Wikipedia

    en.wikipedia.org/wiki/Plasmid_preparation

    The most common method is alkaline lysis, which involves the use of a high concentration of a basic solution, such as sodium hydroxide, to lyse the bacterial cells. [15] [16] [17] When bacteria are lysed under alkaline conditions (pH 12.0–12.5) both chromosomal DNA and protein are denatured; the plasmid DNA however, remains stable.

  7. Chelex 100 - Wikipedia

    en.wikipedia.org/wiki/Chelex_100

    Chelex resin is often used for DNA extraction in preparation for polymerase chain reaction by binding to cations including Mg 2+, which is an essential cofactor for DNases. Chelex protects the sample from DNases that might remain active after the boiling and could subsequently degrade the DNA, rendering it unsuitable for PCR.
