Tip
CHES shows a pKa (25°C) of 9,55 which makes CHES useful as a buffering component in the pH range between 8.6 to 12.0. CHES interferes in the protein quantification according to Lowry. It is used in crystallisation of Phosphotriesterase (50mM) or in the chemical modification of Bacteriorhodopsin (10mM). Synonyms are: 2-(Cyclohexylamino)ethanesulfonic acid; 2-(N-Cyclohexylamino)ethanesulfonic acid. Other buffers are: BES, BICIN, MOPS, CAPS, CHAPS
