In biological experiments, it is important to maintain the pH of the solutions used. Buffers, which are mixtures of weak acids and their appropriate conjugate bases, are commonly used in these experiments. Most biological reactions occur when the buffer is at its effective pH range of 6 to 8. Furthermore, the acids and bases used in the biological reaction should not produce chelates with metal ions. For these reasons, Dr. Good developed several aminoethane and aminopropane sulfonic acids that are now widely used for biological research and analysis. Goods buffers have the following characteristics: 1) High water-solubility. 2) Low cell membrane permeability. 3) Consistent acid-base dissociation constants. 4) Low metal chelating capability. 5) High chemical stability. 6) Low absorption spectra in UV and visible regions.
