Thermo Scientific™ RNA Gel Loading Dye (2X)
Description
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.
Highlights
- Two-color tracking of DNA, RNA migration during electrophoresis
- No DNA, RNA masking during gel exposure to UV light
- Denaturation of DNA, RNA due to the presence of formamide

Frequently Asked Questions (FAQs)
Each of Thermo Scientific DNA and RNA ladders has a recommended voltage given in V/cm. Please refer to the gel picture in the product information sheet. V/cm stands for the amount of voltage recommended per cm of the distance between the two electrodes of the gel box (not gel length).
Thermo Scientific DNA and RNA ladders have 5′-phosphate and 3′-hydroxyl groups.
Thermo Scientific 2X RNA Loading Dye contains 95% formamide as a denaturing agent and hence cannot be used for native gel electrophoresis.
