PIPES is a zwitterionic N-substituted aminosulfonic acid "Good" buffer. PIPES is used to buffer glutaraldehyde fixative solutions when fixing plant and/or animal tissue samples. This will help prevent the loss of lipids. It is also used to buffer glutaraldehyde and formaldehyde when…

MOPS is a zwitterionic amino acid which acts as one of the "Good" buffers. It is a structural analog to MES. However, MOPS is a more suitable biological buffer than MES because the pH range is closer to pH 7.4.

MES is a zwitterionic buffer. One of the "Good" buffers developed for biological applications. It has the advantages of maximum water solubility and minimum solubility in all other solvents, minimal salt effects, minimal change in pK with temperature, chemically and enzymatically stable,…

Tris has been useful as buffers in a wide variety of biological systems. Uses include pH control in vitro and in vivo for body fluids and in buffering systems for electrophoresis applications. Tris has been used as a starting material for polymers, oxazolones (with carboxylic acids) and…

HEPES is a zwitterionic organic chemical buffering agent. HEPES is widely used in many biochemical reactions and as a buffering agent in some cell culture media.
