How to Use Phenol/Chloroform for DNA Purification

WebThe following protocol is one of the longest-established methods of DNA extraction and works well with a wide range of solid tissues. Proteins are digested with proteinase K and extracted with phenol chloroform. DNA is then precipitated with ethanol. WebJan 11, 2024 · However, DNA extraction was performed using the phenol–chloroform method, which has several disadvantages: the extraction process is complex, the clot needs to be washed, the reagents are toxic, and the quantification cycle (Cq) values of qPCR assays are variable when the assay is repeated. motorcycle rallies in texas 2023 https://steve-es.com

Preparation, Purification, and Quantitation of DNA & RNA

Aqueous samples, lysed cells, or homogenised tissue are mixed with equal volumes of a phenol:chloroform mixture. This mixture is then centrifuged. Because the phenol:chloroform mixture is immiscible with water, the centrifuge will cause two distinct phases to form: an upper aqueous phase, and a lower organic phase. The aqueous phase rises to the top because it is less dense than the organic phase containing the phenol:chloroform. This difference in density is why phen… WebOct 15, 2024 · The major differences among samples could be attributed to inter-individual variations rather than DNA extraction protocols.
