Human ON-TARGETplus RTF - Tyrosine Kinases

The only ready-to-use siRNA screening libraries available

Ideal for labs who want to carry out a few screens but lack high-throughput capabilities.

Human ON-TARGETplus RTF Tyrosine Kinase siRNA Library includes siRNA reagents targeting tyrosine kinases; a large family of evolutionarily conserved enzymes that activate and deactivate a number of different metabolic pathways by catalyzing the phosphorylation of specific tyrosine residues on key effector proteins. Tyrosine kinases are typically classified into membrane-bound or non-membrane-bound groups and are found in nearly every mammalian cell type.

RTF siRNA libraries are provided as multiple single-use plate sets – just rehydrate, and add cells. The pre-plated format reduces hands-on time for faster screening results.

ON-TARGETplus modifications combine sense-strand inactivation with a novel seed-region modification. This patented siRNA approach is the best strategy to prevent off-target effects caused by both the sense and antisense strands while maintaining high-silencing potency.


  • Six ready-to-use 96-well plate sets provided for two triplicate screens
  • Pre-plated, validated RNAi controls included
  • No aliquoting necessary, just resuspend and add cells
  • siRNA reagents provided in clear plates at 6.25 pmol per well (50 nM final screening concentration)
  • Black or white clear-bottom plates available to support assays involving fluorescent or luminescent detection

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

Our siRNA knockdown guarantee

siGENOME and ON-TARGETplus siRNA reagents (SMARTpool and three of four individual siRNAs) are guaranteed to silence target gene expression by at least 75% at the mRNA level when demonstrated to have been used under optimal delivery conditions (confirmed using validated positive control and measured at the mRNA level 24 to 48 hours after transfection using 100 nM siRNA).

Note: Most siGENOME and ON-TARGETplus siRNA products are highly functional at 5 to 25 nM working concentration.

Eight cell lines were transfected with control siRNAs targeting Cyclophilin B using RTF plates. Good cellular viability and effective target silencing were accomplished under optimized conditions. Gene knockdown is normalized to GAPDH expression. Cell plating densities are indicated in parentheses. Gene expression was determined 48 hours posttransfection by branched DNA assay (Panomics Quantigene® Reagent System) (blue bars). Cell viability was determined by alamarBlue® metabolic assay (gold circles).
