GMP Buffer
GMP Manufactured Process ChemicalMES, Monohydrate, GMP Grade
Product Code: MESM-4220 | Previously: ME4220
Intended For Use In Pharmaceutical GMP Processes
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.
