WebMay 25, 2024 · By adding EDTA to the DNA extraction solution, the destructive action of these enzymes can be inhibited by chelating these ions. Therefore, the most suitable medium in DNA solution is the solution containing EDTA, which has the right amount of solutes, because DNA is more stable and soluble in saline solutions. In industry, EDTA is mainly used to sequester (bind or confine) metal ions in aqueous solution. In the textile industry, it prevents metal ion impurities from modifying colours of dyed products. In the pulp and paper industry, EDTA inhibits the ability of metal ions, especially Mn , from catalysing the disproportionation of hydrogen peroxide, which is used in chlorine-free bleaching. In a similar manner, EDTA is added to some food as a preservative or stabiliser to prevent catalytic oxidativ…
