Human ON-TARGETplus RTF - Ubiquitin Conjugation Subset 3
Ideal for labs who want to carry out siRNA screens but lack high-throughput capabilities
The Human ON-TARGETplus RTF Ubiquitin Conjugation 3 siRNA Library contains the majority of known ubiquitin ligases. RING finger and most RING finger-like E3 ligases form a site of interaction with E2s through a platform generated as a consequence of coordination of two zinc ions. A20-like proteins, also included in this set, contain a single coordination site for zinc. This set contains siRNA for well-known E3s such as BRCA1, MDM2 and CBL family members.
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

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 µnM siRNA).
Note: Most siGENOME and ON-TARGETplus siRNA products are highly functional at 5 to 25 µnM working concentration.
Plate layout of ON-TARGETplus RTF siRNA Libraries
Validated control siRNAs and pools are pre-dispensed into column 1 of each RTF Library plate, providing a consistent baseline for screening and assay efficiency.
Reverse Transfection Format is highly effective across cell lines
Reverse transfection Format was used to assess control gene silencing (Cyclophilin B; blue bars) and viability (yellow dots) across eight cell lines under optimized conditions. In all cases, effective target gene knockdown was achieved with low cytotoxicity.
