용도
Biological buffer.
일반 설명
MES is one of the Good′s buffers, the most extensively used biological buffers. MES is a zwitterionic N-substituted aminosulfonic acid with a morpholinic ring. It does not form complexes with majority of the metals used in environmental and biological studies. It is easily soluble in water and has minimum lipid solubility, making it impermeable to membranes.
Purification Methods
Crystallise MES from hot EtOH containing a little water. The picrate crystallises from EtOH and has m 178.8-182o. [Malkiel & Mason J Org Chem 8 199 1943, Beilstein 27 III/IV 370.]
