Description

Silencer™ Negative Control No. 2 siRNA

Invitrogen™ Silencer™ Negative Control #2 siRNA has no significant sequence similarity to mouse, rat, or human gene sequences. The control has also been tested in cell-based screens and proven to have no significant effect on cell proliferation, viability, or morphology.

  • Nontargeting with limited sequence similarity to known genes
  • Validated for use in human, mouse, and rat cells
  • Functionally proven to have minimal effects on cell proliferation and viability
  • HPLC purified, duplexed, and ready to use
Negative control siRNAs are essential for determining transfection efficiency and to control for the effects of siRNA delivery. In siRNA screening applications, negative control siRNAs are also critical for setting the “hit“ threshold that determines whether an siRNA is considered to have a positive, negative, or neutral effect in a particular assay.

Accessory Product: Silencer™ siRNA Screening Control Panel (SKU#AM4640)
The Silencer™ siRNA Screening Control Panel includes seven negative control siRNAs, and is for those researchers performing siRNA screens that employ hundreds or thousands of siRNAs per experiment. Because negative control siRNAs may have unintended effects in a particular assay, a negative control siRNA should be carefully chosen. The Silencer™ siRNA Screening Control Panel simplifies this process. As an added benefit, a positive control siRNA to human, mouse, and rat KIF11 (Eg5) is included in the panel. Knockdown of KIF11, which encodes a kinesin family motor protein, leads to mitotic arrest. Silencer™ control siRNAs are unmodified 21-mers; they are designed to be used with Silencer™ siRNAs, BLOCK-iT™ siRNAs, and other unmodified 21mer siRNAs. If you are using other siRNA products, such as Invitrogen™ Silencer™ Select siRNAs or STEALTH RNAi™ siRNAs, we recommend that you use control siRNAs designed for use with those siRNAs for more reliable experimental results.

Frequently Asked Questions (FAQs)

How critical is it to include positive and negative controls in siRNA experiments?

A positive control siRNA such as the Silencer Select GAPDH siRNA will demonstrate efficient transfection and help to optimize transfection conditions. A negative control siRNA is necessary to serve as a baseline for gene expression.
What are the positive and negative controls I should use with my Silencer or Silencer Select siRNA experiment?

We offer several negative and positive controls for both Silencer and Silencer Select siRNA.

For Silencer siRNA positive control:
- Silencer Firefly Luciferase (GL2 + GL3) siRNA (Cat. No. AM4629, 5nmol)
