Description and Uses

ACES is a zwitterionic buffering agent used in biochemistry and molecular biology that was first selected and described by Good et al. It is a paraacetamide buffer suitable for environments with a pH of 6.1 - 7.5. ACES can be used as a buffer component in cell culture media for use in agarose and polyacrylamide electrophoresis and in isoelectric focusing of proteins. It forms complexes with most common metals, and the formation constant should be taken into account when using such buffers in solutions containing metal ions.

ACES is used as a Good's buffer is an ideal separator in the resolution of protein systems, a zwitterionic compound used in biochemical and biological research.
