Web1. jan 2013 · Next, organic extraction is carried out, in which a mixture of phenol, chloroform and isoamyl alcohol is added. DNA separates into the aqueous phase, while most other contaminants separate into the organic phase. An optional treatment with RNase A ensures that the sample is free from RNA contamination. DNA is then recovered by ethanol ... WebIsopropanol precipitation of DNA Alcohol precipitation is commonly used for concentrating, desalting, and recovering nucleic acids. Precipitation is mediated by high concentrations of salt and the addition of either isopropanol or ethanol.
WebThe methods included solid-phase DNA adsorption (QIAamp), sequential protein and DNA precipitation (Puregene), magnetic bead adsorption (Dynabeads), phenol-chloroform extraction, and single-step proteinase K digestion. WebOur results demonstrate that phenol:chloroform with an ethanol precipitation prior to extraction is the most efficient method in terms of yield and cost, using urine as a non-invasive source of DNA and providing an alternative diagnostic method at a low cost.
Web1. júl 2009 · DNA precipitate is collected by centrifugation, and excess salt is rinsed with 70% ethanol and centrifuged to discard the ethanol supernatant. The DNA pellet is then dissolved with TE buffer or sterile distilled water [ 3 ]. The use of guanidinium isothiocyanate in RNA extraction was first mentioned by Ulrich et al. (1977).
