Custom siRNA

Custom siRNA using your sequences or sequences we have bioinformatically designed for you.

Product Benefits

  • Complimentary designs with the Rosetta algorithm*
  • Simplified transfection optimization with 11 Positive Control siRNA
  • Distinguish sequence-specific silencing from non–specific effects with 8 negative control siRNA
  • Custom services allow for flexibility in experimental set up

*The proprietary Rosetta siRNA Design Algorithm utilizes Position-Specific Scoring Matrices and knowledge of the seed region to predict the most specific and effective sequences for your target genes. The algorithm’s rules were developed utilizing empirical data collected from gene silencing experiments carried out over three years.

Product Features

**Depending on manufacturing site, PAGE may be used to assess siRNA duplexes.

Product Pools***

A popular pooled format is 4 duplexes at 5 nmol each combined into one tube (20 nmol pooled)) plus the exact same 4 duplexes also at 5 nmol each in separate tubes (another 20 nmol individual). However, our sophisticated liquid handlers allow for a wide range of other possibilities.
