General description
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.
Application
MES Hydrate has been used:
• As a component of extraction buffer in the extraction of the enzyme BACE1
• As a component of the reaction mixture for the measurement of 5,10-methenyltetrahydrofolate synthetase (MTHFS) enzyme activity in fibroblasts
• As a component of MES coupling buffer during the coupling of mAb or GST-fusion proteins to carboxylate-modified polystyrene latex (CML) beads
