MES (hemisodium)

MES (2-Morpholinoethanesulphonic acid) hemisodium is a kind of amphoteric ion buffer, the buffer capacity ranging pH 5.5-7.0. As a Good's buffer, MES hemisodium is widely used in biochemistry and molecular biology experiments, such as cell culture, enzyme activity determination, electrophoresis and protein studies[1][2].
