一般說明
Tris 是生物化学和分子生物学中已确立的基础标准品和缓冲液。可单独作为缓冲液使用，也可作为混合缓冲液配方的组分，如 Tris-EDTA (TE) 缓冲液、Tris-acetate-EDTA (TAE) 缓冲液、Tris-borate-EDTA (TBE) 缓冲液等。它纯净，基本稳定，相对不吸湿，具有很高的当量。
應用
Trizma ® 碱用作以下研究的缓冲液：
- 电泳转移法特异性鉴定淀粉脱支酶 α 的同工酶-淀粉酶和 9-淀粉酶。
- 聚丙烯酰胺凝胶中脂蛋白的电泳分离。
- 制备 pH 值为 8 的 TRIS 缓冲液。
其他說明
所有缓冲液的 pH 值都取决于温度和浓度。Tris 缓冲液，温度每降低 1°C，pH 值增加约 0.03 个单位，每稀释十倍 pH 值降低0.03-0.05 个单位。
对于精确的应用，使用经过精心校准的 pH 计和玻璃/甘汞组合电极。

An electrophoretic transfer technique was developed for the specific identification of isozymes of starch debranching enzyme, alpha-amylase, and beta-amylase. Amylolytic enzymes are separated by native polyacrylamide slab gel electrophoresis and proteins in gels are electrophoretically transferred through starch-containing polyacrylamide gels.
