三羟甲基氨基甲烷盐酸盐 [TRIS盐酸盐]，Trizma® hydrochloride；reagent grade, ≥99%, crystalline

Tris hydrochloride is mainly required for preparation of buffer at physiological range of 7.3 to 7.5. The prepared buffer is compatible with biological fluids. It is of importance to laboratories as a standard pH solution.

 

所有缓冲液的pH值都与温度和浓度有关。对于 Tris 缓冲液，温度每降低 1°C，pH 就会增加约 0.03 单位，每稀释 10 倍，pH 会降低 0.03-0.05 单位。
对于一些精准的应用，请使用经过仔细校准的pH计和玻璃/甘汞组合电极。

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.

Tris hydrochloride has been used as a buffer solution for staining procedure, reduction and alkylation studies and in situ hybridization procedure.­
