| 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. |
