Description

The Silencer Select siRNAs are classic 21-mers which incorporate the latest improvements in siRNA design, off-target effect prediction algorithms, and chemistry. A choice of Silencer Select siRNAs are available—Pre-Designed or Validated. Silencer Select Pre-Designed siRNAs are guaranteed-to-silence based on their proven design while the Silencer Select Validated siRNAs are functionally tested to reduce target gene expression. Sets of Silencer Select siRNA Libraries are also available in tubes or plate for high throughput screening. The Silencer Select Positive and Negative Control RNAs should be included in every siRNA experiment.

The benefits of using Silencer Select siRNAs include:

  • Potent—up to 100-fold more potent than currently available siRNAs and fewer off-target effects
  • Most specific—LNA® chemical modifications reduce off-target effects by up to 90%
  • Reliable—demonstrated improvements in consistency and reliability of phenotypic results
  • Guaranteed—100% guaranteed to silence, the best guarantee in the industry

Note: Silencer Pre-Designed & Validated siRNAs are designed using our first-generation algorithm and DO NOT include any chemical modifications. They are recommended for completing in vitro RNAi studies that were started using Silencer siRNAs. For new studies we recommend Silencer Select siRNAs.
