Figure . Silencing efficiency of siCONTROL™ Cyclophilin B siRNA in the presence of increasing amounts of siGLO™ RISC-Free™ siRNA. HeLa cells were co-transfected with a constant concentration of siRNA (100 nM) comprised of increasing ratios of Cyclophilin B siRNA:RISC-Free™ (or Non-Targeting) siRNA. For comparison, a parallel set of samples included cells transfected with cyclophilin B siRNA alone. After 24 hours, cyclophilin B mRNA levels were measured using a branched DNA assay (Genospectra).When unmodified, nontargeting siRNA is included in the transfection mix, the level of targeted gene silencing is reduced in a dose-dependent fashion suggesting competition for the silencing machinery. In contrast, when RISC-Free™ siRNA is a part of the transfection mix, no effect on the silencing efficiency (no competition) is observed.

原厂资料：
The Thermo Scientific siGLO Green Transfection Indicator is a fluorescent oligonucleotide duplex that localizes to the nucleus, thus concentrating its signal to permit unambiguous visual assessment of uptake into mammalian cells. They are ideal for use in optimization experiments to determine ideal siRNA or microRNA reagent transfection conditions and for monitoring relative delivery efficiency during silencing experiments. siGLO Green (6-FAM) Transfection Indicator exhibits nearly 100% signal localization to the nucleus and represents an ideal choice for lipid-mediated transfection optimization.
Transfection Indicators are intended as a qualitative indicator of delivery and should not be used for quantitative determination of siRNA uptake.
Highlights
• FAM-labeled Transfection Indicator exhibits nearly 100% signal localization to the nucleus with traditional transfection reagents
• Absorbance/Emission Max is 494/520 nm, a FITC filter can be used
• Specially modified, fluorescent RNA duplex for simplified transfection assessment - without performing a functional assay
• Fluorescent signal localizes to the nucleus as an unmistakable signal of uptake
• Use as an indicator of transfection success in any RNAi experiment
