CHES is a zwitterionic buffering agent used in biochemistry and molecular biology. It is a cyclohexylamine buffer that is useful for a pH range of 8.6 – 10.0 and commonly used to study enzymatic processes above physiological pH. CHES displays only weak or negligible complexation capabilities for some metals making it a suitable non-coordinating buffer for use in most solutions containing metal ions. CHES displays high affinity for the iodoacetate binding site of liver alcohol dehydrogenase, protecting the enzyme from inactivation by iodoacetic acid.
