Figure.DharmaFECT siRNA transfection reagents are very effective in delivering siRNA with minimal effect on cell viability. DharmaFECT formulations 1-4(DF1, DF2,DF3, and DF4) were used to transfect 100 nM siRNA targeting GAPDH in a variety of cell lines.At 72 hours, GAPDH expression (bars) was determined by branched DNA assay (Panomics Quantigene® Reagent System) and cell viability (data points) was determined by alamarBlue™ (Biosource International).
Figure . DharmaFECT (A) is effective across a broader range of experimental conditions when compared to a lipid from a leading manufacturer (B). Several cell densities and lipid volumes were investigated to determine optimal transfection conditions, shown by the shaded blue boxes. Three cell densities of HepG2 cells were transfected with GAPD siRNA (100nM) using a range of volumes of DharmaFECT 4 and a lipid from a leading manufacturer. GAPD mRNA levels (bars) were assessed by branched DNA assay (Panomics uantigene® Reagent System) and cell viability (data points) was determined by alamar- Blue™ (Biosource International)."
To attain efficient and reliable siRNA or microRNA transfection, we offer DharmaFECT transfection reagents. Thermo Scientific DharmaFECT 2 Transfection Reagent achieves highly effective transfection of siRNA and microRNA reagents in many common cell types. DharmaFECT 2 Transfection Reagent is chemically distinct from the other DharmaFECT formulations, providing an alternative when DharmaFECT 1 does not achieve optimal results, and is ideal to include in transfection optimization experiments prior to RNAi screening or other high-value experiments.
Highlights
• Optimized for small RNA (siRNA or microRNA) delivery at low concentrations
• Low toxicity – Maintain cell viability with formulations specially formulated to deliver siRNA
• Highly efficient delivery – Achieve robust uptake for reliable RNAi results
While DharmaFECT 1 is the most all-purpose transfection reagent (demonstrating efficient, low-toxicity delivery to over 80% of validated cell types), DharmaFECT 2, 3, and 4 are available to support a wider range of cell types. Distinct formulations permit more thorough optimization of transfection for novel cell types, high-value experiments and RNAi screening.
Consult the DharmaFECT Cell Type Guide of transfection optimization results for the DharmaFECT formulation that is recommended for your cell type.
