一般說明
Bis-Tris丙烷缓冲液,也称BTP,是一种两性离子生化缓冲液,用于各种实验室应用(特别是分子生物学、生物化学和电泳)中pH的调节。其广泛的缓冲范围为pH 6.3至9.5,这一点归因于其接近的pKa值6.8 (pKa1)和 9.0 (pKa2)。这一广泛的缓冲范围令其能够在各种实验中保持稳定的pH条件。
此外,Bis-Tris丙烷是一种水溶性缓冲物质,在提高限制酶的稳定性和活性中起关键作用。具体而言,其缓冲能力对于于需要pH水平低至 6-7的实验有利。Tris 缓冲液在pH 低于7.5时缓冲能力不足,在温度变化时pKa波动很大,与其相比Bis-Tris丙烷是一种更好的选择。此外,它可与盐酸缓冲液一起用于稳定法尼基二磷酸,特别是从酿酒酵母中分离时。特别是,它可作为配体并与镧系稀土元素(III)形成双核羟基复合物。
