Genome wide siRNA coverage against human, mouse and rat
Trilencer-27 siRNA kit contains Dicer-Substrate duplexes that provide two critical improvements over the use of traditional 21mer siRNA designs. It takes advantage of the natural processing by Dicer producing 10-fold higher potency and specificity than shorter 21mer RNAi forms. The 27mer duplexes also evade the radar of the mammalian interferon response when expressed in mammalian cells and initiates strong and specific gene silencing.
By its optimal design, 27mer siRNA has the advantages of improved efficacy and minimal interferon response. Learn more about Dicer-Substrate technology in this Nature Publication.
Features & Benefits:
- Genome wide coverage against human, mouse and rat
- 27mer Dicer-substrate duplex -- higher potency & minimal interferon response
- Guaranteed gene knockdown (≥70%)
Each of our siRNA product comes as a kit. It contains 3 unique 27mer siRNA duplexes with the size of 2 nmol each, one negative control and one buffer. Each gene specific siRNA is labeled as the kit catalog number plus a/b/c. For example,

OriGene guarantees that at least two of the three Dicer-Substrate duplexes in the kit will provide at least 70% or more knockdown of the target mRNA when used at 10 nM concentration by quantitative RT-PCR when the TYE-563 fluorescent transfection control duplex (cat# SR30002) indicates that >90% of the cells have been transfected and the HPRT positive control (cat# SR30003) provides 90% knockdown efficiency. For non-conforming siRNA, requests for replacement product must be made within ninety (90) days from the date of delivery of the siRNA kit. To arrange for a free replacement with newly designed duplexes, please contact Technical Services at firstname.lastname@example.org. Please provide your data indicating the transfection efficiency and measurement of gene expression knockdown compared to the scrambled siRNA control (quantitative RT-PCR data required).
