Webgenerally you have the highest buffering capacity when pKa = pH. Thus inn your case HEPES is a good buffer, Tris will also be okay. Note that the pKa is temperature … WebPhosphate-buffered saline ( PBS) is a buffer solution (pH ~ 7.4) commonly used in biological research. It is a water-based salt solution containing disodium hydrogen phosphate, sodium chloride and, in some formulations, potassium chloride and potassium dihydrogen phosphate. The buffer helps to maintain a constant pH.
