Custom microRNA (miRNA) knockdown probes from Exiqon

Pre-designed inhibitors for specific suppression of all microRNAs in miRBase and our proprietary miRPlus™ sequences
Sophisticated and innovative design
Unmatched high efficacy even for AT-rich microRNA targets
High and uniform potency enables multiplexing at low concentrations with minimal risk of off-target effects
Superior specificity and biological stability for long lasting antisense activity
End-labeling option for easy control of transfection efficiency

Features

Custom miRCURY LNA™ microRNA Inhibitors and Power Inhibitors are available for specific knockdown of your own microRNA or other small RNA sequences. These microRNA inhibitors are generated using Exiqon’s in-house design software applying the same novel sophisticated design algorithms used for our pre-desgined microRNA Inhibitors. This ensures the optimal combination of length, sequence and LNA™ positioning in the custom microRNA inhibitor. Moreover, they are designed to have excellent sequence specificity and biological stability, while keeping the self-annealing properties to a minimum.

The miRCURY LNA™ microRNA Power Inhibitors have phosphorothioate (PS) backbones that stabilize the inhibitor. We therefore recommend these inhibitors in difficult applications where:

the transfection efficiency is limiting (primary cells, cells growing in suspension)
the microRNA target is highly expressed
the phenotypic readout that takes place >72 h after transfection (cell differentiation)
regular microRNA inhibitors fail

Coverage

Our custom microRNA inhibitors and Power inhibitors are delivered as ready-to-label or as 3' or 5' pre-labeled fluorescein (6-FAM) oligonucleotides. Requests for alternative labels please contact us. All custom microRNA inhibitors are HPLC-purified and desalted and delivered in tubes containing 5 nmol dried-down oligonucleotide ready for transfection or electroporation using standard techniques

Before submitting your order, please check if a pre-designed microRNA inhibitor targeting your sequence is available. Pre-designed miRCURY LNA™ microRNA microRNA Inhibitors and Power Inhibitors are available for all microRNA sequences annotated in miRBase (v.13.0).
