Phenol function in rna extraction
WebTRIzol is a widely used chemical solution used in the extraction of DNA, RNA, and proteins from cells. The solution was initially used and published by Piotr Chomczyński and Nicoletta Sacchi in 1987.. TRIzol is the brand name of guanidinium thiocyanate from the Ambion part of Life Technologies, and Tri-Reagent is the brand name from MRC, which was founded by … Extraction of DNA containing samples with acidic phenol results in the denaturation of the DNA, and once denatured, the DNA partitions to the organic phase. This is a key feature of many RNA purification protocols, which is one of the reasons acidic buffer-saturated phenol is used. Zobraziť viac I suggest dissolving your RNA in Tris-EDTA and add 1 v chloroform before centrifugation.
