Excipient
ICH-Q7 GMP Manufactured ProductMES, Monohydrate, LBLE
GMP Excipient Grade
Low Bioburden, Low Endotoxin, GMP Manufactured
Product Code: MESM-3250
Intended For Use As An Excipient
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.
