Tris-Borate-EDTA (TBE) buffer is commonly used in DNA extraction procedures to provide a suitable pH and ionic environment for DNA stability. TBE helps to maintain the integrity of DNA by preventing degradation, facilitating electrophoresis, and providing conductivity for the separation of DNA fragments.
Maintaining the osmotic pressure to prevent the cell form bursting.
Dithiothreitol (DTT) is a reducing agent used in DNA extraction to break disulfide bonds in proteins, helping to denature and separate them from DNA. This helps to prevent protein contamination in DNA samples, ensuring the purity of isolated DNA.
2-propanol is used in DNA extraction to precipitate DNA from the mixture. When added to the sample, it causes the DNA molecules to come out of solution and form a visible clump that can be easily separated. This step allows for the separation and purification of DNA from other components in the sample.
The function of phenol-chloroform is to denature proteins and extract DNA into the organic phase, while the function of isopropanol is to precipitate DNA by causing it to become insoluble in the solution.
Buffer AP1 is used in DNA extraction to lyse cells and release nucleic acids. It contains a chaotropic salt that disrupts cell membranes and denatures proteins, allowing DNA to be released from the cells. Buffers with chaotropic salts help to preserve the integrity of DNA during the extraction process.

In a DNA extraction, the purpose of a buffer is to solubilize DNA as well as RNA. Because of this, it prevents the DNA for degrading.

Chloroform is used in DNA extraction to separate the DNA from other cellular components. It is primarily used to remove proteins by denaturing them, allowing the DNA to be purified and collected in the aqueous phase of the extraction. Chloroform is a key reagent in the organic extraction step of DNA isolation procedures.
Triton X-100 is used as a lysis buffer for DNA separation.
Ascorbic acid, also known as Vitamin C, is used in DNA extraction to prevent DNA degradation by acting as an antioxidant. It helps to protect the DNA sample from damage caused by reactive oxygen species that can break down the DNA molecules. This ensures the integrity and stability of the DNA during the extraction process.
Phenol chloroform isoamyl alcohol helps to separate proteins and lipids from DNA during extraction. Phenol denatures proteins, chloroform aids in partitioning DNA, while isoamyl alcohol prevents foaming. This combination allows for efficient extraction of DNA from biological samples.
Maintaining the osmotic pressure to prevent the cell form bursting.
DNA is not soluble in isopropyl alcohol. It will precipitate out when you add this solvent. Once out of solution you can centrifuge it down and collect the pellet of DNA.
Dithiothreitol (DTT) is a reducing agent used in DNA extraction to break disulfide bonds in proteins, helping to denature and separate them from DNA. This helps to prevent protein contamination in DNA samples, ensuring the purity of isolated DNA.
2-propanol is used in DNA extraction to precipitate DNA from the mixture. When added to the sample, it causes the DNA molecules to come out of solution and form a visible clump that can be easily separated. This step allows for the separation and purification of DNA from other components in the sample.
TBE buffer in gel electrophoresis is used to maintain pH of te solution and prevents the denaturation of smale fragments of DNA.
