Tris-硼酸-EDTA缓冲溶液

MFCD00236358

NA.21

TBE running buffer is the most commonly used buffer for DNA and RNA polyacrylamide gel electrophoresis. TBE is used with non-denaturing or denaturing (7 M urea) gels. It is also routinely used for DNA automated sequencing gel. Tris-Borate-EDTA buffer has been used for pulsed-field gel electrophoresis (PFGE). Applied voltages of less than 5 V/cm are recommended for maximum resolution.
TBE电泳液是DNA和RNA聚丙烯酰胺凝胶电泳最常用的缓冲液。TBE用于非变性或变性(7M 尿素)凝胶。 它通常也用于DNA自测序凝胶。 TBE可以用于琼脂糖凝胶，但是不推荐用于回收核酸的制备胶。
将TBE储存浓缩溶液稀释到1×TBE电泳缓冲液，生成的缓冲液含有89mM Tris-硼酸和2mM EDTA，pH8.3。 5X或10X储存液也可以加入丙烯酰胺/甲叉双丙烯酰胺储存液，用来制成PAGE胶。 为了达到最大的分辨率，推荐电压小于5V/cm(电极单元间距离)。

采用经生物技术性能认证的 Trizma 碱(产品代码 T6066)、分子生物学试剂硼酸(产品代码 B6768)和 EDTA 二钠盐(产品代码 E5134)制备。
