EDTA and EGTA solutions are chelating agents that bind divalent metal ions to inhibit metal-dependent enzymes or prevent unwanted reactions.
- Chelate Ca²⁺ and Mg²⁺ ions
- Protect proteins and nucleic acids from metal-dependent degradation
- Available in aqueous buffer formulations
- Useful in cell lysis and enzyme inhibition
Commonly used in cell lysis, protein purification, and reactions sensitive to divalent cations.
