일반 설명
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.
애플리케이션
Trizma® base was used as buffer for the following studies:
- Electrophoretic transfer for the specific identification of isozymes of starch debranching enzyme, α-amylase and 9-amylase.
- Electrophoretic separation of lipoproteins in polyacrylamide gels.
- Preparation of TRIS buffer having pH 8.
기타 정보
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.
