  2. Acid guanidinium thiocyanate-phenol-chloroform extraction

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

    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. It is widely used for isolating RNA (as well as DNA and protein in some cases).

  3. Trizol - Wikipedia

    en.wikipedia.org/wiki/Trizol

    The correct name of the method is guanidinium thiocyanate-phenol-chloroform extraction. The use of TRIzol can result in DNA yields comparable to other extraction methods, and it leads to >50% bigger RNA yield. [5] [6] An alternative method for RNA extraction is phenol extraction and TCA/acetone precipitation. Chloroform should be exchanged with ...

    en.wikipedia.org/wiki/Guanidinium_thiocyanate

    A commonly used method is guanidinium thiocyanate-phenol-chloroform extraction. It is not strictly necessary to use phenol or chloroform if extracting RNA for Northern blotting or DNA for Southern blot analysis because the gel electrophoresis followed by transfer to a membrane will separate the RNA/DNA from the proteins. Additionally, since ...

  5. RNA extraction - Wikipedia

    en.wikipedia.org/wiki/RNA_extraction

    The extraction of RNA in molecular biology experiments is greatly complicated by the presence of ubiquitous and hardy RNases that degrade RNA samples. Certain RNases can be extremely hardy and inactivating them is difficult compared to neutralizing DNases. In addition to the cellular RNases that are released there are several RNases that are ...

    en.wikipedia.org/wiki/DNA_microarray

    In this example total RNA is isolated (both nuclear and cytoplasmic) by guanidinium thiocyanate-phenol-chloroform extraction (e.g. Trizol) which isolates most RNA (whereas column methods have a cut off of 200 nucleotides) and if done correctly has a better purity.
