General description

N-(2-Acetamido)-2-aminoethanesulfonic acid (ACES) is a zwitterionic buffer used in biochemistry and molecular biology research. It is one of the Good′s buffers with a pH range of 6.15 - 8.35. The preferred range of ACES buffer in an aqueous solution is 6.1 - 7.5.

Application

ACES has been used:

  • as a component of buffered charcoal yeast extract (BYCE) agar for plating bacteria culture and Buffered Yeast Extract (BYE) liquid medium to culture bacteria
  • to study the impact of the pH shift on the thermal inactivation of bacterial (Bacillus subtills) spores
  • as a buffer system to study the depolymerization of starch by α-amylase during exposure to hydrostatic pressure.
It is also suitable for use: as buffers for both agarose and polyacrylamide gel electrophoresis; in the isoelectric focusing of proteins; in the analysis of bacterial autolysins in a discontinuous sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) system.

Other Notes

The product is intended for laboratory use only, and it is not suitable for drug, household, or other purposes.

Growth of Legionella spp. on buffered charcoal yeast extract medium supplemented with alpha-ketoglutarate and formulated with 3-(n-morpholino)propanesulfonic acid (MOPS), 3-(n-morpholino)-2-hydroxypropanesulfonic acid (MOPSO), or n-(2-acetamido)-2-aminoethanesulfonic acid (ACES) buffer was similar. With three exceptions, growth was no different in buffered yeast extract
