Intended for Use in Biopharmaceutical & Biotechnological Applications and Products

MES Monohydrate is used as a high purity, GMP Reagent Grade product. MES Monohydrate is a zwitterionic buffer that is not absorbed through cell membranes and is virtually transparent in UV light. MES is a buffering agent used in many biological and biochemical applications. It is also used as a running buffer for denaturing gel electrophoresis. The characteristics of low UV absorptivity, minimal reactivity, stable pH and solubility in water allow MES Monohydrate Excipient to be used as a Good’s buffer.
