  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. Lysis buffer - Wikipedia

    en.wikipedia.org/wiki/Lysis_buffer

    It may be the most widely used lysis buffer. The solubilizing agent is NP-40, which can be replaced by other detergents at different concentrations. Since NP-40 is a nonionic detergent, this lysis buffer has a milder effect than RIPA buffer. It can be used when protein functions are to be retained with minimal disruption. [9] Recipe: [9] 150 mM ...

  4. HEPES - Wikipedia

    en.wikipedia.org/wiki/HEPES

    HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) is a zwitterionic sulfonic acid buffering agent.It is one of the twenty Good's buffers.HEPES is widely used in cell culture, largely because it is better at maintaining physiological pH despite changes in carbon dioxide concentration (produced by aerobic respiration) when compared to bicarbonate buffers, which are also commonly used in ...

  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. Buffer solution - Wikipedia

    en.wikipedia.org/wiki/Buffer_solution

    A buffer solution is a solution where the pH does not change significantly on dilution or if an acid or base is added at constant temperature. [1] Its pH changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical ...

  7. Good's buffers - Wikipedia

    en.wikipedia.org/wiki/Good's_buffers

    All buffering agents achieve their function because they contain an acidic group (acetate, phosphate, sulphonate ..) or a basic group (amino, pyridyl ..). A consequence of this is that they can form complexes with the biologically important ions Na +, K +, Mg 2+ and Ca 2+ and can compete for the metal ion contained in a metalloprotein. In fact ...

    A number of studies have linked red wine consumption with heart health benefits, including reduced LDL (known as “bad”) cholesterol levels, better blood pressure and blood vessel function and ...

  9. P1 phage - Wikipedia

    en.wikipedia.org/wiki/P1_phage

    P1 is a temperate bacteriophage that infects Escherichia coli and some other bacteria. When undergoing a lysogenic cycle the phage genome exists as a plasmid in the bacterium [1] unlike other phages (e.g. the lambda phage) that integrate into the host DNA. P1 has an icosahedral head containing the DNA attached to a contractile tail with six ...
