Silencer Select siRNAs - Up to 100X Higher Potency

Silencer Select siRNAs Provide Up to 100X Higher Potency Compared to Other siRNAs.
Silencer Select siRNAs to 10 different targets and siRNAs from two other suppliers to the same 10 different targets were individually transfected into HeLa cells in triplicate at the indicated siRNA concentration. mRNA knockdown levels were tested 48 h later as described in Figure 1. Average percent mRNA remaining is shown for each set of siRNAs.

• Are up to 100X more potent than competitor siRNAs
• Can be routinely transfected at ≤5 nM and retain their silencing power
• Result in fewer off-target effects when used at these lower concentrations
• Cost less per experiment than siRNAs used at higher concentrations
