WebTRIzol ® reagent is an acid-guanidinium-phenol based reagent ideally designed for the extraction of RNA (as well as DNA and protein) from various biological sample inputs. The low pH (acidic) of TRIzol ® controls to separate RNA from DNA and protein, while a high pH can cause RNA and DNA to be isolated together. The guanidinium salt serves as a … WebOther methods use ion-exchange chromatography to separate the mixture into its various components, so the DNA is removed from the proteins and RNA in the extract (Figure 3). Removing contaminants by organic extraction and enzyme digestion The standard way to deproteinize a cell extract is to add phenol or a 1 : 1 mixture of phenol and chloroform.
WebIn RNA extraction procedures, Acid Phenol:Chloroform:IAA aids in the removal of DNA (it partitions into the organic phase), helps to stabilize the interface, and prevents foaming when mixing. Preparation of phenol for use in molecular biology applications is a time-consuming and often hazardous procedure due to its toxic and corrosive nature.
