Gene silencing with self-delivering siRNA

A single reagent for guaranteed gene knockdown in any cell type

Accell™ siRNA by Dharmacon™ is uniquely modified to facilitate passive uptake into the cell – eliminating the need for viral vectors, cytotoxic transfection or electroporation techniques. Simply add one reagent to silence any human, mouse or rat gene, in nearly any cell line.

Accell benefits:
  • Single reagent – no viral vector, transfection or electroporation required 
  • Easy delivery – simply add the appropriate amount to your cells
  • Guaranteed gene silencing – all Dharmacon siRNA are guaranteed to knockdown the target gene
Ideal for:
  • Difficult-to-transfect cell types – primary, neuron, immune cells & iPSCs
  • Gene knockdown – simplified workflow for guaranteed results
  • Extended-duration silencing – low toxicity enables multiple dosing up to 30 days

Accell gene silencing workflow

Accell gene silencing workflow
Accell gene silencing workflow
(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.

The power of Accell siRNA lies in the simplicity of it's workflow

To achieve guaranteed target gene knockdown, simply combine Accell siRNA stock solution with Accell siRNA delivery media to a recommended 1µM working concentration. Then add Accell delivery mix directly to cells and incubate for 72 hours.

Delivery may be inhibited by the presence of BSA in serum. Optimization with serum-free media formulations (Accell Delivery Media) or < 2.5% serum in standard media is recommended.  Full-serum media may be added back after 48 hours of incubation mRNA silencing is achieved by 72 hours, with optimal protein knockdown observed around 96 hours.
