Ultra High Range RNA Ladder —Now Extended to 15 kb

The Ultra High Range RNA ladder, comprising four single-stranded RNAs (6k, 9k, 12k and 15k), is synthetically generated through in vitro transcription from a blend of linear DNA templates. This ladder serves as an effective tool for determining the size of single-stranded RNAs in native agarose gel electrophoresis. Visualization can be achieved using UV light post-ethidium bromide staining or nucleic acid safety dye staining. Notably, it acts as a reliable ssRNA size standard on native agarose gels.
