Intended for Use in Diagnostic and Laboratory Applications

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. These are general specifications. BioBuffer Solutions will customize our products to meet your quality based requirements.
