An aqueous solution of 0.22µm membrane-filtered ethylendiaminetetraacetic acid (EDTA), sodium salt. By forming complexes with metal ions, EDTA inhibits metal-dependent enzymatic reactions. EDTA complexes metal ions at a 1:1 molar ratio.Nucleic acids are normally stored in TE buffer that contains 1mM EDTA, which prevents degradation of nucleic acids by metal dependent nucleases.
Recommended for: Termination of metal dependent enzymatic reactions; Protection of DNA against metal dependent nucleases.
