Overview

useful pH range 5.5 - 6.7 pKa 6.1

product 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 has been used as a component of the elution buffer used to elute plasma from α2-macroglobulin affinity column. It has been used as an activation buffer during antibody conjugation to microparticles. MES has been used in the functionalization of microchannels during the creation of microfluidic-integrated surface plasmon resonance (SPR) platform for pathogen detection.
