The MessageMuter shRNA Production Process

The MessageMuter shRNA Production Kit utilizes a simple and unique 3-step process (Figure 2) that yields shRNA in about 4 hours. A 17-base T7 Promoter Oligo is annealed to a DNA oligo designed by the user using detailed instructions provided. The ends of the annealed duplex are "filled-in" using the Exo-Minus Klenow to obtain a linear dsDNA with a T7 RNAP promoter at its 5'-end. Following in vitro transcription, the RNA produced spontaneously forms a hairpin structure (shRNA). Following clean-up, the shRNA is ready for transfection into cultured cells. The MessageMuter shRNA kit provides reagents to produce 10 shRNAs in sufficient quantities for hundreds of transfections.


  • Production of shRNA, micro RNA (miRNA) studies, or other applications.


  • Produces shRNA in vitro using one user-designed oligo and one in vitro transcription reaction.
  • No need for annealing of sense and anti-sense RNA strands as required by other in vitro transcription-based methods.
