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.
Other Notes
