15 uses of MES Buffer you didn't know



MES was one of the first zwitterionic buffers described by Norman E. Good in 1966. Nowadays it is commonly used in biological and biochemical research, but… what is MES actually suitable for? We collected reliable information from renowned academic sources in order to help scientists understanding better MES’ characteristics and suitability for different biotechnology applications (cell culture, chromatography, and others). Check out our findings!

 

MES basic information:

  • CAS Number: 4432-31-9
  • Molecular Weight: 195.2
  • Formula: C6H13NO4S
  • Useful ph range: 5.5 - 6.7
  • pKa (25°C): 5.9 - 6.3

 

What is MES recommended for?

  1. As most of anionic buffers, MES it is suitable for cation exchange chromatography and hydroxylapatite chromatography1
  2. Used in gel-filtration chromatography
  3. Used in phosphocellulose column chromatography2
  4. Used in hydrophobic interaction chromatography2
  5. Used in SDS-PAGE3
  6. Used in for fluorescence microscopy4
  7. Suitable as a noncoordinating buffer in solutions with metal ions
  8. Suitable for the investigation of redox processes5
  9. Used to prepare culture medias, since it is not metabolized by bacteria and eukaryotic cells6
  10. Used in culture media for plant cells at low concentrations7
  11. Used for mammalian cell culture8
  12. Suitable for most toxicity studies9
  13. Used for in vitro dissolution testing of liposomes10
  14. MES interacts with peptide backbone of bovine serum albumin leading to a net stabilization of the protein11
  15. MES does not form radical species, making it suitable for redox studies5

Which concerns should you have before choosing MES for your research?

  • It can be oxidized by H2O2, but since the oxidation happens slowly, no considerable impact on biological/biochemical systems is expected to happen12
  • It can modify lipid interactions13
  • It inhibits the connexin channel activity in rat liver cells when it is in the protonated form14
  • It interferes with phenolic oxidation by peroxidases15
  • It is toxic to most plants at high concentrations6


Useful tips about MES:

  • Low ionic mobility at high concentrations
  • Low conductivity at high concentrations
  • Weak binding with most metal ions
  • Considered a good alternative to cacodylate, a highly toxic buffer
  • Considered a good alternative to citrate, a buffer that binds to some proteins and forms complexes with some metals
  • Considered a good alternative to maleic acid, a buffer with high UV-absorption
