설명

일반 설명

Tris(hydroxymethyl)aminomethane, commonly known as Trometamol, Tris base, or Trizma^® base, serves a pivotal role in diverse research applications as a biological buffer. Its optimal pKa of 8.1 makes it a preferred choice for formulating buffers like Tris-acetate-EDTA (TAE) and Tris-borate-EDTA (TBE), ensuring the maintenance of pH within the physiological range (pH 7 - 9), applicable to a wide spectrum of living organisms. Despite its utility, researchers need to exercise caution in protein studies, as Tris has the potential to interfere with the activity of specific enzymes.

Tris base may find application as basimetric standard, independently as a buffer and as a crucial component in mixed buffer formulations, including Tris-EDTA (TE) buffer, TAE buffer, TBE buffer, among others. Its attributes include purity, essential stability, and a relative non-hygroscopic nature, making it a dependable choice in laboratory settings. In these environments, Tris base is indispensable for preparing buffers compatible with biological fluids and serves as a standard pH solution. It facilitates various laboratory procedures such as lactate dehydrogenase assays, in situ hybridization, and protein extraction from cells. The versatility of Tris base extends to cell biology, biochemistry, and protein research contributing significantly to studies involving cell membrane permeability and buffer preparation.

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.
