WebThe organic extraction method is the most tried-and-tested method for RNA extraction and removal of cellular proteins. Here, RNA isolation is achieved through organic extraction followed by RNA precipitation. This technique involves lysis or extraction in a monophasic solution of phenol and guanidine isothiocyanate. Chloroform is then added. WebA two step purification system can easily be used to combine two methods of your purification strategy. A classical approach is the combination of a capture with a polishing step. Some examples for the first and the second step are listed in . In principle Tab. 1
