MES, Monohydrate - GMP Buffer
BIO PHARMA GRADE | ME4220 | CAS# 145224-94-8
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.
These are general specifications. BioSpectra will customize our products to meet your quality based requirements.
