MES is a zwitterionic buffer.
MES is regarded as one of the "Good" buffers developed for biological applications. It has the advantages of: midrange pKa, maximum water solubility and minimum solubility in all other solvents,minimal salt effects, minimal change in pK with temperature chemically and enzymatically stable, minimal absorption in visible or UV spectral range.
Soluble in water (0.5 M or higher yields a clear and colorless solution).
