** Life Technologies guarantees that when you purchase three Stealth RNAi® Pre-Designed siRNAs to the same target, at least two of those three independent, nonoverlapping siRNAs will silence the target mRNA by 70% or more. To qualify for the guarantee, siRNAs must have been transfected at ≥20 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. We also recommend the use of an appropriate negative control, such as one of the three Stealth RNAi® Negative Controls to normalize message knockdown.

Life Technologies guarantees that when you purchase two Silencer Select Pre-designed siRNA to the same target, then those two siRNAs will silence the target mRNA by 70% or more. To qualify for the guarantee, siRNA's must have been transfected at ≥5 nM and mRNA levels detected 48h 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.
