ACES is a zwitterionic buffering agent used in biochemistry and molecular biology that was first selected and described by Good et al. It is an acetamido buffer that is useful for a pH range of 6.1 – 7.5. ACES is used as buffering component in cell culture media, in both agarose and polyacrylamide electrophoresis, and in isoelectric focusing of proteins. ACES forms a complex with most common metals and formation constants should be taken into account when using this buffer in a solution containing metal ions. ACES absorbs UV light at 230 nm.
