Ammonium Sulfate Protein Precipitation: The key to Salting-Out

Salt precipitation can be a very powerful tool to purify proteins by precipitation. Ammonium sulfate is usually the salt of choice since it is cheap, very soluble in water, and is able to become much more hydrated (interacts with more water molecules) than almost any other ionic solvent. In practice, ammonium sulfate is either added directly as a solid or added as a (usually) saturated ...

DNA extraction - Wikipedia

The first isolation of deoxyribonucleic acid (DNA) was done in 1869 by Friedrich Miescher. Currently it is a routine procedure in molecular biology or forensic analyses. For the chemical method, there are many different kits used for extraction, and selecting the correct one will save time on kit optimization and extraction procedures.

For efficient incorporation by DNA polymerase, free dNTPs should be present in the reaction at a concentration of no less than 0.010–0.015 mM (their estimated K m) (Figure 4). When using non-proofreading DNA polymerases, fidelity can be improved by lowering dNTP concentrations (0.01–0.05 mM), as well as proportionally reducing Mg 2+.

The Basics of DNA Extraction – Alaska BioPREP Virtual Textbook

Bacterial cells have no nucleus. Their DNA is organized in rings or circular plasmids, which are in the cytoplasm. The DNA extraction process frees DNA from the cell and then separates it from cellular fluid and proteins so you are left with pure DNA. The three basic steps of DNA extraction are 1) lysis, 2) precipitation, and 3) purification.
