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.

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.
