RNA Gel Loading Dye (2X)

货号：R0641

规格：1 mL

价格：448

产品类型：RNA提取

品牌：Thermo Fisher

Thermo Scientific 2X RNA Loading Dye is recommended for preparation of RiboRuler RNA ladders and RNA samples for electrophoresis on agarose or polyacrylamide gels. It contains the tracking dyes bromophenol blue and xylene cyanol FF as well as the intercalating dye ethidium bromide. In most denaturing agarose gel systems, bromophenol blue migrates slightly faster than human 5S rRNA, whereas xylene cyanol FF migrates slightly slower than 18S rRNA.2X RNA Loading Dye contains the denaturing agent formamide, which allows RNA fragments to separate according to size even during non-denaturing electrophoresis. Formamide also stabilizes RNA.
