WebThe phenol extraction step of the tissue lysates can also present problems. The high DNA and RNA content of these tissues causes the homogenates to be unusually viscous. Extraction of such viscous homogenates sometimes results in incomplete phase separation. Adding more lysis solution and/or re-extracting with phenol:chloroform:IAA will help ... WebOrganic extraction of nucleic acids is historically the most common, tried-and-true method for RNA isolation and removing cellular proteins. This technique requires homogenization of your sample in a phenol-containing solution (usually phenol-chloroform). The phenol-chloroform mixture is immiscible with water, therefore when centrifuged, the ...

WebPhenol/chloroform extraction from mouse tail biopsies. This protocol yields a highly purified DNA preparation from mouse tail biopsies. 1. Remove 0.5 mm of tail into polypropylene microfuge tube (do not mince). (The tubes must have tight-fitting caps, so that there are no leaks in steps 3 and 7 below.) 2. Add 0.5 ml DNA digestion buffer with ... WebPhenol: Phenol (also called carbolic acid) is an aromatic organic compound with the molecular formula C 6 H 5 OH.
