Thermo Fisher, 15575020, UltraPure™ 0.5M EDTA, pH 8.0

UltraPure™ 0.5M EDTA, pH 8.0 is designed for molecular biology and biochemistry workflows requiring controlled chelation of divalent metal ions. The sterile-filtered aqueous solution contains 0.5 M EDTA prepared by dissolving disodium EDTA dihydrate in distilled, deionized water and adjusting the pH to 8.0 with sodium hydroxide. EDTA binds divalent metal ions that can participate in metal-dependent enzymatic reactions, making the solution useful in workflows involving nucleic-acid gel electrophoresis, chromatin biology, and blotting. The ready-prepared concentration eliminates the need to dissolve and titrate a concentrated EDTA stock each time a working buffer is made. This specific configuration is a multipack of four 100 mL bottles rather than a single 100 mL bottle. Its 0.5 M concentration allows measured aliquots to be diluted into compatible buffers or reactions at the concentration required by an established procedure. The product provides a consistent high-concentration chelator stock for repeated laboratory preparation and is intended for research use rather than diagnostic procedures.
