ON-TARGETplus RTF Optimization Plates - Human

Optimize conditions and select controls for your RTF screen

Three 96-well plates with pre-plated controls in Reverse Transfection Format (RTF) for optimization of conditions for your RNAi screen with RTF Human siRNA Libraries

Optimization is essential for any RNAi screen. The ON-TARGETplus Optimization Plates are ideal for selection of the best transfection conditions and controls for screens in human cells using RTF siRNA Libraries. The plate layout enables the testing of cell density and transfection reagent amount on the same plate while also identifying the best non-targeting siRNA control for your assay.


  • Three ready-to-use replicate 96-well plates; 6.25 pmol siRNA per well (50 nM final concentration)
  • Provided in clear or clear-bottomed white or black-walled plates to support assays involving fluorescent or luminescent detection
  • Positive control pool targets Human cyclophilin B (Accession NM_000942)
  • Four non-targeting siRNAs and a non-targeting pool with ON-TARGETplus modifications to minimize off-target effects
For a diagram of the RTF Library Plate layout, see Figure 1 on the Supporting Data tab.

Experimental considerations

DharmaFECT Cell Culture Reagent (DCCR) is recommended for use with RTF libraries to dilute transfection reagents prior to use. DCCR may be purchased separately or accompanying your RTF Optimization Plates

DharmaFECT transfection reagentsare highly recommended for use with RTF libraries and should be purchased separately. Refer to the DharmaFECT Cell Type Guideto find the appropriate formulation for your cell type.

The pre-plated controls in the RTF Optimization Plates permit assessment of multiple cell densities and transfection reagent amounts to optimize your RNAi screening conditions. You can additionally evaluate multiple non-targeting control siRNAs to determine the best negative control for your assay.
