General description

ADA is a zwitterionic buffer used in biochemistry and molecular biology. It is one of the Good buffers developed in the 1960′s to provide buffers in the pH range of 6.15 - 8.35 for wide applicability to biochemical studies. The pioneering publication by Good and co-workers describes the synthesis of ADA and its physical properties. The useful range of ADA buffer in aqueous solution is 6.0 - 7.2.

Application

Biological buffer component with sodium hydroxide and sodium chloride (pH 5.67-7.57, useful pH range 6.4-7.4). Used to prepare immobilized pH gradients.

Preparation Note

This product is soluble in 1 M NaOH (160mg/mL), yielding a clear, colorless solution.
