Description

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.
