DNA Damage Response siRNA library targets genes involved in the DNA damage and repair pathways. This includes damage surveillance, damage recognition and signalins of tumor progression, apoptosis, senescence, andg, signal effector genes, repair genes, and genes involved in dissociation and resolution of DNA repair complexes. The damage response pathway is of high interest in studie cell-cycle checkpoint regulation.
Accell siRNA achieves what no other RNAi product can claim: delivery into difficult-to-transfect cells without transfection reagents, virus, or electroporation. Researchers around the world are achieving targeted gene silencing in cells that had previously been beyond the reach of conventional RNAi products due to toxicity caused by transfection reagents or undesirable viral responses.
- Accell siRNA enters cells without the need for transfection reagents, virus (or viral vectors), or instruments
- Proven performance in neuronal, immunological, primary, and other difficult-to-transfect cell types
- Extended-duration knockdown with optimized continuous application
- Available as SMARTpool siRNA reagents or a Set of 4 siRNAs in 96 well plates
For a complete list of target genes in this siRNA Library, please contact Technical Support or your local Sales Representative.
- Accell siRNA works at a higher concentration than conventional siRNA; recommended 1 µM working concentration
- Delivery may be inhibited by the presence of BSA in serum. Optimization studies with serum-free media formulations (Accell Delivery Media) or < 2.5% serum in standard media is recommended
- Full-serum media can be added back after 48 hours of incubation. Optimal mRNA silencing is typically achieved by 72 hours or up to 96 hours for protein knockdown
Cell types demonstrating effective silencing with Accell siRNA
Internal validation and peer-reviewed publications report numerous successes with difficult-to-transfect cell types. See the Citations tab for a list of published references.
The Accell siRNA application protocol simplifies targeted gene knockdown
(1) Combine Accell siRNA with Accell delivery media (or other low- or no-serum media). (2) Add Accell delivery mix directly to cells, and incubate for 72 hours.
