* We guarantee that when you purchase two Silencer Select pre-designed siRNAs to the same target, those two siRNAs will silence the target mRNA by 70% or more. To qualify for the guarantee, the siRNAs must have been transfected at ≥5 nM and mRNA levels detected 48 hours post-transfection. Real-time RT-PCR is recommended but not required for this application. Customers must also show sufficient knockdown with a positive control siRNA to demonstrate transfection efficiency. If the guaranteed level of knockdown is not observed and an appropriate positive control is successful, a new Silencer Select siRNA sequence will be synthesized free of charge. This guarantee does not extend to any replacement product or to the sample kit. Terms and conditions apply. For complete details, go to
