EDTA buffer is used to chelate (bind) metal ions and maintain pH balance in biological and chemical analyses. It is a critical solution in DNA/RNA isolation, enzyme studies and cell culture experiments.

It is one of the fundamental solutions used in molecular biology, biochemistry and chemistry laboratories to teach students the role of buffer solutions.

It is a buffer solution widely used in biotechnology laboratories to provide protein purification, cell culture media, and stabilization in enzymatic reactions.
