Human Duet siRNA Library - Ubiquitin Conjugation Subset 2

Screen with the two most reliable siRNA reagents available


Paired screening libraries of siGENOME and ON-TARGETplus siRNA for guaranteed silencing of human F-box and SOCS box E3 ubiquitin ligases.
Duet siRNA Libraries are paired libraries of siGENOME and ON-TARGETplus siRNA SMARTpool reagents. The Human Duet Ubiquitin Conjugation Subset 2 siRNA Library contains siRNAs targeting human F-box and SOCS box E3 ligases, known and predicted substrate recognition elements for Cul-1 and Cul-2 containing ubiquitin ligases. Well-known members of this E3 ligase family include bTRCP, SKP2, and VHL.

Highlights

  • Increase confidence in your RNAi screen with two guaranteed, highly functional SMARTpool siRNA reagents (Figure 1, Supporting Data)
  • Screen the libraries side-by-side to move high confidence hits through the pipeline faster (Figure 2, Supporting Data)
  • Use the libraries separately as a cost-effective way to obtain two guaranteed collections of highly potent siRNA reagents

siRNA Designs

Both siGENOME and ON-TARGETplus siRNA reagents utilize the same SMARTselection foundational elements for highly functional designs. ON-TARGETplus designs are additionally filtered for specificity-enhancing features that improve the potential for unique designs.

  • In 30% of genes (across the human genome), all eight siRNA sequences targeting a single gene are unique
  • Only 5% of genes share four siRNA sequences across both product lines
  • Even in cases of identical designs, it has been widely demonstrated that ON-TARGETplus specificity-enhancing modifications provide distinct and reduced off-target signatures and thus can be treated as unique silencing reagents

Our siRNA knockdown guarantee

siGENOME and ON-TARGETplus siRNA reagents (SMARTpool and three of four individual siRNAs) are guaranteed to silence target gene expression by at least 75% at the mRNA level when used under optimal delivery conditions (confirmed using validated positive control and measured at the mRNA level 24 - 48 hours after transfection using 100 nM siRNA).

Note: Most siGENOME and ON-TARGETplus siRNA products are highly functional at 5-25 nM working concentration.

siGENOME and ON-TARGETplus SMARTpool reagents are highly potent

siGENOME and ON-TARGETplus SMARTpool reagents are highly potent

siGENOME and ON-TARGETplus SMARTpool reagents are highly potent

Target mRNA knockdown in a screen with siGENOME and ON-TARGETplus SMARTpool siRNA reagents was highly effective, even at concentrations of 2 nM. In extended studies, ON-TARGETplus also was effective in reducing false phenotypes due to off-targets.
