Phenol-chloroform extraction is a liquid-liquid extraction method used in molecular biology. It is used to separate nucleic acids from proteins and lipids. This method is also used to isolate specific compounds, such as antigens. For example, it can be used to separate DNA from RNA. Read on to learn more about this technique. But first, what exactly is it?
It is used for protein purification. The process is effective for separating nucleic acids from proteins. It involves two different phases, one of which contains buffer-saturated phenol. The aqueous phase is low in density, while the soluble protein particles are high in the phenol-chloroform mixture. The resulting organic phase is higher in density, which helps prevent phase inversion. In the same way, aqueous DNA can be extracted with ethanol precipitation.
This method is widely used to separate protein from nucleic acids. It is part of Penn's Chemical Hygiene Plan. In contrast, it has high toxicity and is highly corrosive. But its corrosive properties make it an excellent choice for separating aqueous proteins from nucleic acids. In fact, chloroform can cause a high level of toxicity, and chloroform is highly flammable.
Commercial phenol-chloroform solutions are often equilibrated and sufficient for the extraction. They are usually separated by layers of aqueous water and a layer of phenol/chloroform. Inversion of the layer may occur due to small changes in density. The process can be improved by washing, adding more water, or vortexing. Then, the sample can be poured into a tube.
Because phenol-chloroform is slightly denser than water, it is preferred for RNA extraction. However, it is important to note that chloroform is more stable than silica-based columns. The resulting RNA is less likely to contain contaminants, which may affect downstream applications and negatively impact the quality of your data. This method may not be suitable for some experiments because the sample will be unstable in ethanol.
Fortunately, phenol-chloroform has many advantages. In contrast to phenol-chloroform, chloroform is more stable. It has a lower concentration of aqueous fluid and chloroform is better for extracting proteins. It is also safer for the environment. This method is commonly used for removing protein and is an essential part of Penn's Chemical Hygiene Plan. If your research is sensitive to aqueous samples, this method may be best suited for it.
As a general rule, aqueous samples are mixed with equal volumes of phenol-chloroform mixture. This method is most effective when a single sample contains only water and a little protein. But when DNA-chloroform extraction is performed in a lab that does DNA and RNA extraction, it is important to use acidic phenol to extract both the compounds. These two types of phenol-chloroform solution are not compatible with each other, and must be diluted to ensure that they are equally effective.
