CAS No.:145224-94-8what is of MES MONOHYDRATE with CAS 145224-94-8?
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 to be used as a Good's buffer.

Application
MES monohydrate is a buffering agent used in biochemistry and molecular biology that was selected and described by Good et al. It is a zwitterionic, morpholinic buffer that is useful for a pH range of 5.5 - 6.7 and commonly used for cell culture media, as a running buffer in electrophoresis, and for protein purification in chromatography.
