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 fixing fungal zoospores for fluorescence microscopy and electron microscopy. PIPES tends to give optimal results.
Buffers can be made by adding a solution of base to PIPES free acid, titrating to the appropriate pH.
