General description
Tris is an established basimetric standard and buffer used in biochemistry and molecular biology. It may be used by itself as a buffer or as a component of mixed buffer formulations, such as Tris-EDTA (TE) buffer, Tris-acetate-EDTA (TAE) buffer, Tris-borate-EDTA (TBE) buffer, etc. It is pure, essentially stable, relatively non-hygroscopic and has a high equivalent weight.
Application
Tris base has been used:
- In the preparation of TAE buffer for TAE agarose gel used to run PCR products by gel electrophoresis
- As a component of sample buffer for SDS-PAGE
- In the preparation of IEC (ion-exchange chromatography) buffer
Other Notes
Easily compare specifications for Trizma products with the Trizma specification table.
The pH values of all buffers are temperature- and concentration-dependent. For Tris buffers, pH increases about 0.03 unit per °C decrease in temperature, and decreases 0.03-0.05 unit per ten-fold dilution.
For precise applications, use a carefully calibrated pH meter with a glass/calomel combination electrode.
