RNA Visualization

RNA Mango

The most advanced RNA tracking, visualization and pull down technology.

Technology for studying the diverse cellular roles of RNA has lagged behind the tools for studying DNA and proteins, but innovative researchers are working to change that! One such researcher is Dr. Peter Unrau of Simon Fraser University. He and his team have created RNA Mango, a novel technology with a number of useful applications.


Key Features

RNA Mango technology is based on the specific binding of the RNA Mango Aptamer and a Thizole Orange (TO) bi-functional dye. The main features of this technology is the tight binding between the dye and aptamer (KD ≈ 3nM) , and the strong ~1000X enhancement of the dye’s fluorescence when bound to the Mango aptamer (Fluorescent enhancement FE=1,100).

The TO dye has a number of other desirable properties including:

  • Small size
  • Lack of toxicity
  • Plasma and nuclear membrane permeability
  • Short intracellular half-life
  • The accessibility of a broad wavelength range simply via substitutions and alterations to the TO structure

TO1-biotin is the standard variety of TO dye for RNA Mango experiments; other dye variants will also be available soon.

Product Information

  • The RNA Mango Aptamer
    The RNA Mango Aptamer
    The system has two components: the RNA Mango aptamer, and the TO-1 dye. The dye only fluoresces when bound to the Mango aptamer.
  • Tagging Your RNA
    Tagging Your RNA
    For mRNA inset the tag into the 3'UTR. For structured non-coding RNA replace a stem-loop that is not essential to the RNA function.
  • Application: RNA Visualization
    Application: RNA Visualization
    Express RNA of interest (with Mango Tag) using a vector or CRISPR Knock-In. Soak cells in TO-1 Biotin dye to illuminate RNA of interest localization
  • pApplication: RNA-RNA or RNA-protein complex pulldown
    Application: RNA-RNA or RNA-protein complex pulldown
    Express RNA of interest (with Mango Tag) using a vector or CRISPR Knock-In. Lyse the cells, and recover RNA of interest with bound RNA or proteins using streptavidin breads
