MES, Monohydrate - Excipient

BIO EXCIPIENT GRADE | ME3220 | CAS# 145224-94-8

INTENDED FOR USE AS AN EXCIPIENT

Product-image

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.
