EDTA buffer, short for Ethylenediaminetetraacetic acid buffer, is a versatile chelating agent commonly used in biochemistry and molecular biology. It forms stable complexes with divalent metal ions such as calcium and magnesium, preventing them from interfering with enzymatic reactions and nucleic acid degradation. EDTA buffer is typically prepared as a solution of EDTA disodium salt in water, with a concentration ranging from millimolar to molar levels. It is frequently used in DNA and RNA extraction, protein purification, and enzyme assays to maintain sample stability and integrity. The buffer's ability to sequester metal ions and inhibit nucleases makes it indispensable in laboratory protocols requiring precise metal ion concentrations and protection of biomolecules from degradation.
