General description
Tris是一种已建立的用在生物化学和分子生物学的基质标准和缓冲液。它可以单独用作缓冲液或混合缓冲液配方的组分,如Tris-EDTA(TE)缓冲液、Tris-乙酸盐-EDTA(TAE)缓冲液、Tris-硼酸盐-EDTA(TBE)缓冲液等。它是纯的、基本上稳定的、相对不吸湿的,并且具有很高的相对分子量。
Application
Tris 碱已用于:
- 制备Tris-HCl,其用作裂解缓冲液的组分,用于蛋白质表征
- 制备用于蛋白质印迹的Tris缓冲盐水 Tween-20(TBST)缓冲液
- 制备用于透析以中和蛋白质的TBS(Tris 缓冲盐水)
- 作为核提取缓冲液的组分
Other Notes
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。
