一般說明

Tris Hcl,又称三羟甲基氨基甲烷®盐酸盐,是一种广泛使用的酸性缓冲液,用于制备生理 pH 7.3 ~ 7.5 范围内的缓冲液。Tris Hcl 在 25°C 时的 pKa 为 8.08,pH 值范围为 7.0 至 9.0,与生物体的典型 pH 值相匹配。因此,Tris HCl 是用于各种生物学、细胞培养、生物化学和分子生物学应用的缓冲溶液的重要组成部分。值得注意的是,Tris 碱和 Tris 盐酸盐本身都不能提供足够的缓冲能力。因此,通常将它们组合在一起,在pH值范围为7到9的范围内创建缓冲液,以确保有效的pH控制。

Tris 缓冲液在蛋白质电泳和蛋白质印迹等技术中必不可少。在许多蛋白质印迹方案中,低离子强度 Tris 缓冲液用于蛋白质转移。转移持续时间取决于印迹装置和所研究肽的大小范围。基于 Tris 的缓冲液也常用于 SDS-PAGE 凝胶、运行缓冲液和印迹缓冲液。

此外,Tris 盐广泛用于 DNA 琼脂糖电泳,特别是在制备缓冲液,如 TAE(Tris 醋酸盐/EDTA)和TBE(Tris 硼酸盐/EDTA)。这些缓冲液在各种应用中发挥着关键作用,包括生物化学、蛋白质纯化和电泳。Tris Hcl 应用广泛,对于维持生物系统的pH值和确保生化、细胞培养和分子生物学技术的最佳性能不可或缺。

應用

  • 免疫组织化学分析中的冲洗缓冲液 (1)
  • 在涉及凝胶电泳和生物层干涉测量的生化研究中,作为还原样品缓冲液、裂解缓冲液和洗脱缓冲液的组成部分 (2)

特點和優勢

  • 适用于分子生物学和细胞培养
  • 可用作电泳和蛋白质分离中的缓冲剂组分
  • 经过测试,确定内毒素和总需氧微生物计数
  • 不含 DNase, NICKase、RNase 和蛋白酶
  • 经过测试,确认低水平的重金属污染,确保各种应用的适用性
  • 有效缓冲 7-9 (25 °C),pKa为 8.1 (25 °C)
  • 极易溶于水

包裝

每个试剂盒包含 3 x 100G 样品,每份样品都有唯一的制造商批号。

其他說明

如需了解生化试剂系列的更多信息,请填写此表
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。

In Situ Hybridization of Whole-Mount Mouse Embryos with RNA Probes: Hybridization, Washes, and Histochemistry. This is a protocol describing how to perform in situ hybridization on whole mouse embryos. Here we describe the hybridization procedure, and the localization of the DIG-labeled RNA using a conjugate of anti-DIG Fab antibody and calf intestinal alkaline phosphatase. Enzyme activity of the reporter is detected by a color reaction, resulting in the formation of a water-insoluble purple/blue precipitate. Manipulating the Mouse Embryo - Third Edition
