  2. Boom method - Wikipedia

    en.wikipedia.org/wiki/Boom_method

    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.

  3. Spin column-based nucleic acid purification - Wikipedia

    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.

  4. Solid-phase extraction - Wikipedia

    en.wikipedia.org/wiki/Solid-phase_extraction

    SPE is in fact a method of chromatography, in the sense of having a mobile phase, carrying mixtures through a stationary phase, packed inside a column.The chromatographic process is harnessed to create a solid-liquid extractive technique—allowing separation of a mixture of components by taking advantage of large differences between the solid and liquid phase K eq, or equilibrium constant ...

  5. DNA extraction - Wikipedia

    en.wikipedia.org/wiki/DNA_extraction

    Solid phase extraction such as using a spin-column-based extraction method takes advantage of the fact that DNA binds to silica. The sample containing DNA is added to a column containing a silica gel or silica beads and chaotropic salts. The chaotropic salts disrupt the hydrogen bonding between strands and facilitate the binding of the DNA to ...

    en.wikipedia.org/wiki/List_of_purification...

    Sublimation is the process of changing of any substance (usually on heating) from a solid to a gas (or from gas to a solid) without passing through liquid phase. In terms of purification - material is heated, often under vacuum, and the vapors of the material are then condensed back to a solid on a cooler surface.

  8. Solid-phase reversible immobilization - Wikipedia

    en.wikipedia.org/wiki/Solid-phase_reversible...

    Solid-phase reversible immobilization, or SPRI, is a method of purifying nucleic acids from solution. It uses silica- or carboxyl-coated paramagnetic beads, which reversibly bind to nucleic acids in the presence of polyethylene glycol and a salt. A common application of SPRI technology is purifying samples of DNA amplified by PCR for sequencing ...

  9. Solid-phase microextraction - Wikipedia

    en.wikipedia.org/wiki/Solid-phase_microextraction

    Solid-phase microextraction sampling. Solid phase microextraction, or SPME, is a solid phase extraction sampling technique that involves the use of a fiber coated with an extracting phase, that can be a liquid or a solid (), [1] which extracts different kinds of analytes (including both volatile and non-volatile) from different kinds of media, that can be in liquid or gas phase.
