应用

Trizma被用于配制pH范围在7.5和8.5之间的缓冲液。 Tris缓冲液被广泛用于细胞和分子生物学,如蛋白质和核酸提取和纯化等过程。 Trizma缓冲液也可用于柱层析和凝胶电泳。三羟甲基氨基甲烷盐酸盐被用作制备各种类型Tris缓冲液的通用试剂。

其他说明

便于将 Trizma HCl 产品规格与 Trizma HCl 规格表进行比较
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。
作为提取缓冲液的组分,如DNA或RNA的苯酚提取;通过SDS-PAGE鉴定 体外 翻译产物时,作为分离胶和浓缩胶的缓冲液成分
