Description and Uses

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.

MES Monohydrate has been used:

  • To adjust the pH of growth medium to 5.5-7.0 in an in vitro cell wall stress assay
  • As a buffering agent to stabilize enzymatic solutions
  • As a component of PAGE running buffer
