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)."
Thermo Scientific DharmaFECT Set of 4 Transfection Reagents includes one vial of each chemically distinct DharmaFECT formulation, and is offered to help determine the appropriate transfection reagent for any cell types where a recommended formulation is not available, or when experimental conditions call for re-optimization of siRNA or microRNA transfection. Our online resources for over 35 cell lines can help determine the best single DharmaFECT Transfection Reagent formulation for your research, but if you are unable to find recommendations for your cell line, it is advisable to optimize delivery with DharmaFECT 1, 2, 3, and 4 Transfection Reagents.
Highlights
• Four distinct formulations for transfection optimization studies in new cell types or experimental conditions
• Optimized for small RNA (siRNA or microRNA) delivery at low concentrations
• Low toxicity – Maintain cell viability with formulations specially formulated to deliver siRNA
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.
