  • Custom microRNA

    Use our online ordering tool to easily enter your mature microRNA and have our proprietary miRIDIAN mimic modification pattern applied to you sequence.

    Multiple scales and processing options are available, as well as a wide variety of 5’ and 3’ modifications.

Additional microRNA modulation tools are available by Technical Support quote

If you are looking for a standard miRIDIAN microRNA Mimic or Hairpin Inhibitor for a human, mouse, or rat microRNA and you do not require any additional modifications or special processing, use the search function in the upper right-hand corner of the page to find pre-designed microRNA modulation tools.

For custom inhibitors, Accell inhibitors and stabilized mimics, please request a quote online or contact Technical Support.

For Custom miRIDIAN microRNA mimics order using our online tool.

Extended options for enhancing your microRNA mimic or inhibitor

  • Stabilized Mimics: Add stabilizing modifications to a miRIDIAN Mimic for additional stability in nuclease-rich environments
  • Accell Inhibitors: Add Accell modifications to a microRNA inhibitor for delivery into cells without a transfection reagent

Advantages of custom synthesis

  • Target a microRNA in an alternative species
  • Introduce mismatches to study microRNA biomechanics
  • Select In vivo processing and large-scale synthesis for animal studies
  • Apply a wide range of chemical modifications 
  • Custom miRIDIAN microRNA mimics

    Online ordering for custom miRIDIAN mircoRNA mimics.

  • Contact Technical Support for stabilized mimics, to add mismatches within your mimic sequence, Accell inhibitors and custom miRIDIAN hairpin inhibitors.

Application notes

Modulating endogenous miRNA targets with miRIDIAN microRNA mimics and inhibitorsMicroRNAs (miRNAs) have been shown to regulate gene expression through both translational attenuation and messenger RNA (mRNA) degradationReciprocal microRNA Modulation Identifies Gene Targets in a Biological ContextThrough their effect in down-regulation of gene transcripts, microRNAs play an important role in a range of biological processes such as developmentmicroRNA targets in stem cell differentiationMicroRNAs are non-coding RNAs that provide critical translational regulation within the cell. Screening microRNAs for determinants of osteogenesisMicroRNAs (miRNAs) are endogenous non-coding RNAs that modulate gene expression through the RNA interference pathway.
