26239-55-4 - Application:

ADA (CAS: 26239-55-4) is buffer for biological systems and chelator for metals. 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. Used to prepare immobilized pH gradients. ADA is a biological buffer with a pKa of 6.9 at 20 degrees Celsius and a pH in the range of 6.0~7.2. This Good's buffer prevents oxidation and irreversible denaturation of proteins while conducting gel electrophoresis. Furthermore studies suggest that ADA interferes with BCA and Lowry protein assays. Also ADA often chelates metal ions such as Mn(II), Cu(II), Ni(II), Zn(II), and Co(II) in a 2:1 at or below physiological pH values. Moreover, ADA is soluble in sodium hydroxide and absorbs UV radiation in the range below 260nm. Can be also used as a pharmaceutical intermediate.
