X-miR is a catalytic microRNA repressor more specific than antagonists.
The X-miR microRNA repressors target specific miRNA with match-driven catalysis and avoids the non-specific effects of typical microRNA antagonists. The X-miR can also be used in synthetic or stably expressed forms for research, drug-discovery, and therapeutics development- no chemical modifications required.
Repressing microRNA
Mature microRNA's can be specifically repressed using Oligoengine's exclusive X-miR products. The X-miR is designed to bind to your target microRNA with perfect sequence complimentarity and avoid pitfalls associated with microRNA antagonists
Stable or Transient X-miR
Since chemical modifications or alternative chemistries are NOT required, the X-miR microRNA repressor can be constitutively expressed by inducible pX-miR or delivered as synthetic RNA.
Synthetic RNA X-miR: $499 each
Inducible pX-miR Clones: $599 each
Cloning oligos: $249 /oligo pair
X-miR Serum Stability
Transient use of synthetic X-miR RNA is prolonged by the exonuclease resistance characteristic of its novel structure.
Custom designed X-miRs
Thousands are pre-designed for specificity against individual miRNAs, but with new miRNAs discovered weekly, Oligoengine is ready to design X-miRs specific to your needs.
Getting started with X-miR microRNA repressors
X-miR oligos can be used transiently as RNA or expressed constitutively from inducible pX-miR vectors. Oligoengine offers design assistance for any custom X-miR as well as a library of pre-designed versions.
Mature microRNA
As non-coding regulatory elements, microRNA can be specifically repressed by X-miR oligo constructs.
Basic X-miR Design
Oligoengine designs X-miR specifically to a targeted nucleotides of a mature microRNA.
X-miR Design Overview
Serum Stability
MicroRNA repression efficacy and duration is prolonged by exonuclease resistance.
X-miR Results
Gene modulation results by microRNA repression will vary depending upon function of the microRNA itself. The X-miR libraries contains ready-to-use designs targeting 'mature', 'minor', pre-miRNA', or 'broad' nucleotide regions of each microRNA gene.
Price List.
X-miR constructs are available as transfection-ready clones, ligation-ready oligos, synthetic RNA for transient use.

X-miR Licensing.
X-miR's are based on endoGUIDE technology in the AsymmetricRNAi Platform.
Academic and Non-Profit Licensing Terms
Researchers at academic and non-profit institutions are granted a limited end-user license with the purchase of each X-miR.
Commercial and For-Profit Licensing Terms
Use of the AsymmetricRNAi Platform, including X-miR, by commercial pharmaceutical and biotech companies is subject to specific licensing terms.
Companies can purchase individual X-miR molecules and clones before negotiating a streamlined product use agreement. Additionally, any products, including cell lines, transgenic animals and therapeutic compounds developed using X-miR will be considered as licensed products and subject to a sales royalty by Halo-Bio RNAi Therapeutics Inc.
For more information, please contact OligoEngine for details regarding research-to-therapeutics licensing support.
