siSTABLE Non-targeting siRNA #1

A negative control siRNA with stabilizing modifications for use in vivo and other experimental settings with high nuclease activity. Does not target any known human, mouse, or rat genes.
siSTABLE Non-Targeting siRNA #1 was designed to have a minimum of four mismatches to all human, mouse, and rat genes to avoid non-specific silencing due to off-targets. This negative control siRNA is chemically modified to significantly extend siRNA stability an is recommended for use as a negative control in experiments using siSTABLE modified siRNA against a target gene or where increased stability of the control is desired.


  • BLAST analysis confirms at least 4 mismatches with all known human, mouse, and rat genes
  • Chemically modified to significantly extend siRNA stability
  • Recommended for use as a non-specific control in experiments using siSTABLE modified siRNA against the target gene or where increased stability of the control is desired

Experimental considerations

siRNA-mediated RNAi experiments should include non-targeting siRNA as a control for non-sequence-specific effects. Changes in mRNA or protein levels in cells or tissues treated with these controls reflect a non-specific baseline cellular response to which the levels in cells or tissues treated with target-specific siRNA can be compared.

Stability of siSTABLE siRNA in 100% Human Serum

Stability in 100% serum

The siSTABLE modification pattern dramatically extends the half-life of siRNA in the presence of 100% human serum. Unmodified siRNA degrades almost immediately while siSTABLE siRNA maintains integrity for up to 5 days.
