一般描述
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。
应用
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。
其他说明
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 optically transparent phantom was developed for use in high-intensity focused ultrasound (US), or HIFU, dosimetry studies. The phantom is composed of polyacrylamide hydrogel, embedded with bovine serum albumin (BSA) that becomes optically opaque when denatured. Acoustic and optical properties

Apoptosis has been recognized in normal, including rapidly proliferating, cell populations and is inferred to be potentially responsible for the maintenance of stable cell numbers in tissues with various degrees of proliferative activity. Previous studies performed in rats indicated that

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.
