Evolution of RNAi technology

In comparison to siRNAs and simple stem-loop shRNAs, miRE-based structures mimic endogenous RNAi triggers and thus engage the endogenous RNAi machinery to induce enhanced gene suppression while dramatically decreasing off-target effects.

We can validate for you!

​Mirimus offers shRNA validation services to identify top-performing shRNAs. Using our functional Sensor reporter assay which quantifies single-copy protein knockdown levels (Fellmann, C., et al (2011). Mol Cell), we identify optimized shRNA sequences for reliable in vivo gene suppression.

Each shRNA receives a score indicative of its performance to silence its endogenous target. All validations are performed at single-copy genomic integration which reduces sequence-dependent and -independent off-target effects (Yuan, T., et al (2014). Cancer Discov).
