  2. Alkaline lysis - Wikipedia

    en.wikipedia.org/wiki/Alkaline_lysis

    The steps of alkaline lysis can be summarized as the formation of a pellet, resuspension of the pellet in solution, cell lysis, neutralization, and centrifugation. [ 2 ] Alkaline lysis takes advantage of the small and supercoiled physical composition of plasmid DNA compared to chromosomal DNA, along with its ability to reanneal double stranded ...

  3. Plasmid preparation - Wikipedia

    en.wikipedia.org/wiki/Plasmid_preparation

    Plasmid miniprep. 0.8% agarose gel ethidium bromide-stained.. 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.

  4. Agroinfiltration - Wikipedia

    en.wikipedia.org/wiki/Agroinfiltration

    Agroinfiltration using a promoter::GUS construct in Nicotiana benthamiana" with TBSV p19 (right leaf disc) and without TBSV p19 (left leaf disc).. It's quite common to coinfiltrate the Agrobacterium carrying the construct of interest together with another Agrobacterium carrying a silencing suppressor protein gene such as the one encoding the p19 protein from the plant pathogenic Tomato bushy ...

  5. Buffer P2 - Wikipedia

    en.wikipedia.org/wiki/Buffer_P2

    Buffer P2 is a lysis buffer solution produced by Qiagen.It contains 1% sodium dodecyl sulfate (SDS) (w/v) to puncture holes in cellular membranes, and 200mM NaOH.It is used in conjunction with other resuspension buffers and lysis buffers to release DNA from cells, often as part of the alkaline lysis method of purifying plasmid DNA from bacterial cell culture.

  6. Molecular cloning - Wikipedia

    en.wikipedia.org/wiki/Molecular_cloning

    Molecular cloning takes advantage of the fact that the chemical structure of DNA is fundamentally the same in all living organisms. Therefore, if any segment of DNA from any organism is inserted into a DNA segment containing the molecular sequences required for DNA replication, and the resulting recombinant DNA is introduced into the organism from which the replication sequences were obtained ...

  7. Agarose gel electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Agarose_gel_electrophoresis

    After the experiment is finished, the resulting gel can be stored in a plastic bag in a refrigerator. Electrophoresis is performed in buffer solutions to reduce pH changes due to the electric field, which is important because the charge of DNA and RNA depends on pH, but running for too long can exhaust the buffering capacity of the solution.

  8. Molecular-weight size marker - Wikipedia

    en.wikipedia.org/wiki/Molecular-weight_size_marker

    Buffers can affect the mobility of both the marker and the samples. The pH of the buffer varies with the system used and consequently, each buffer system will have a different effect of the charge of a protein or proteins. [20] In addition, in the case of SDS-PAGE, the binding affinity for SDS can be affected by the buffering system. [20]

  9. Calcium chloride transformation - Wikipedia

    en.wikipedia.org/wiki/Calcium_Chloride...

    It enhances plasmid DNA incorporation by the bacterial cell, promoting genetic transformation. Plasmid DNA can attach to LPS by being added to the cell solution together with CaCl 2. [12] Thus, when heat shock is applied, the negatively charged DNA backbone and LPS combine, allowing plasmid DNA to enter the bacterial cell. [13]
