Although it it a bad idea to use something as unregulated as dish washing liquid for DNA isolation, the scientific principle is that proteins denature (or break up) in the presence of a detergent. Denatured proteins can then be separated from the remainder of the cellular contents by centrifugation. This leaves a supernatant containing mainly nucleic acids (DNA and RNA)
Dish washing liquid is unregulated because we do not know exactly what is in there since it is a commercially available product. There could be other ingredients (like fragrances and other appearance enhancers) that might interfere with DNA isolation.
Laboratory grade detergents like SDS and CTAB are used for DNA isolation
Extraction buffer is added to isolate DNA because it helps break down the cell membrane and nuclear envelope to release the DNA. It also helps in denaturing proteins that may interfere with DNA extraction, and stabilizes the DNA once it is released from the cell.
The wash solution in plasmid DNA extraction is typically used to remove impurities such as proteins, salts, and other contaminants that may be present in the DNA sample. The wash solution helps to ensure that the purified plasmid DNA is free of unwanted substances, improving the overall purity and quality of the extracted DNA.
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.
It serves to break the tissue apart so the DNA can be subsequently extracted.
In DNA extraction, a content/lysis buffer is used to break down the cell wall and cellular membranes to release the DNA from the cells. This buffer typically contains detergents to disrupt the lipid bilayers and proteases to degrade proteins. The content buffer also helps stabilize the DNA and prevent its degradation 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.
Triton X-100 is used as a lysis buffer for DNA separation.

Soap is used in a DNA extraction buffer to break down cell membranes and release DNA from cells. It helps to disrupt the lipid bilayer of the cell membrane, allowing the DNA to be released into the extraction buffer for further processing and purification.
STET buffer is used in plasmid isolation to stabilize the plasmid DNA, prevent degradation by nucleases, and maintain the pH of the solution. It is a commonly used buffer for preserving DNA during the extraction process.
Yes, saline citrate buffer can be used for DNA extraction from bivalve tissue. It helps in breaking down cell membranes and proteins, releasing the DNA for further extraction and purification steps. Ensure to follow a tested protocol for optimal results.
Saline tris EDTA (STE) buffer is used in DNA extraction to provide a suitable environment for DNA stability and prevent DNA degradation. It helps to maintain the pH of the solution, keeps the DNA soluble, and protects it from nucleases that could break it down. Overall, STE buffer helps in the efficient extraction and preservation of DNA from cells.
Buffer AE is a solution used in molecular biology to stabilize DNA and RNA. It typically contains chemicals such as Tris, EDTA, and water to maintain the stability and integrity of nucleic acids during storage or handling. Buffer AE is commonly used in protocols for DNA or RNA extraction and purification.
