Английская Википедия:ACES (buffer)
ACES (N-(2-acetamido)-2-aminoethanesulfonic acid) is a chemical compound that is one of Good's buffers. It was developed in the 1960s to provide buffer solutions with pH ranging from 6.15-8.35 for use in various applications. With a pKa of 6.9, it is often used as a buffering agent in biological and biochemical research. It is a zwitterionic buffer with a useful buffering range of 6.1-7.5. The pioneering publication by Good and his co-workers described the synthesis and physical properties of ACES buffer.[1]
Applications
ACES had been used to develop buffers for both agarose and polyacrylamide gel electrophoresis.[2] ACES use in isoelectric focusing of proteins has also been documented.[3] Use of ACES has been published in a protocol for the analysis of bacterial autolysins in a discontinuous SDS-PAGE system.[4] Potential inhibition of ACES and other Good buffers has been investigated in γ-aminobutyric acid receptor binding to rat brain synaptic membranes.[5]
