Hopax is a manufacturer and supplier of MES (CAS 4432-31-9), a zwitterionic biological buffer often used as a buffering agent in biological and biochemical research.


Uses of MES Buffer: (Read more)

  • Since this Good's Buffer lacks the capability to form a complex with most metal ions, therefore it is recommended for use as a noncoordinating buffer in solutions with metal ions.
  • MES is a popular choice for buffered culture media for bacteria, yeast and mammalian cells.
  • Similarly to Bis-Tris (also manufactured by Hopax), MES is considered an excellent substitute for the highly toxic buffer cacodylate.
  • Used in electrophoresis.
  • Used in different types of chromatography, such as gel-filtration, phosphocellulose column, hydrophobic interaction and cation exchange chromatography.
  • In personal care and cosmetics applications, MES can protect the active ingredients of the formulations against degradation.
