  2. Acid guanidinium thiocyanate-phenol-chloroform extraction

    en.wikipedia.org/wiki/Acid_guanidinium...

    RNA partitions in the aqueous phase, while proteins and DNA partition into the organic/interphase (left). The RNA is then precipitated in an alcohol (right). Acid guanidinium thiocyanate-phenol-chloroform extraction (abbreviated AGPC) is a liquid–liquid extraction technique in biochemistry and molecular biology.

  3. DNA extraction - Wikipedia

    en.wikipedia.org/wiki/DNA_extraction

    The first isolation of deoxyribonucleic acid (DNA) was done in 1869 by Friedrich Miescher. [1] DNA extraction is the process of isolating DNA from the cells of an organism isolated from a sample, typically a biological sample such as blood, saliva, or tissue. It involves breaking open the cells, removing proteins and other contaminants, and ...

    en.wikipedia.org/wiki/Spin_column-based_nucleic...

    Silica in a spin column with water and with DNA sample in chaotropic buffer. Spin column-based nucleic acid purification is a solid phase extraction method to quickly purify nucleic acids. This method relies on the fact that nucleic acid will bind to the solid phase of silica under certain conditions.

  6. DNA separation by silica adsorption - Wikipedia

    en.wikipedia.org/wiki/DNA_separation_by_silica...

    The highest DNA adsorption efficiencies occur in the presence of buffer solution with a pH at or below the pKa of the surface silanol groups. The mechanism behind DNA adsorption onto silica is not fully understood; one possible explanation involves reduction of the silica surface's negative charge due to the high ionic strength of the buffer.

    Estimation of the DNA concentration by comparing the intensity of the nucleic acid band with the corresponding band of the size marker. [34] Analysis of products of a polymerase chain reaction (PCR), e.g., in molecular genetic diagnosis or genetic fingerprinting; Separation of DNA fragments for extraction and purification.

  8. Plasmid preparation - Wikipedia

    en.wikipedia.org/wiki/Plasmid_preparation

    Minipreparation of plasmid DNA is a rapid, small-scale isolation of plasmid DNA from bacteria. [20] [21] Commonly used miniprep methods include alkaline lysis and spin-column based kits. [3] [22] It is based on the alkaline lysis method. The extracted plasmid DNA resulting from performing a miniprep is itself often called a "miniprep".

  9. 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 ]
