eGFP expression silenced by Accell eGFP siRNA

FKHR-U2OS cells (BioImage) were treated with 1 µM Accell eGFP Control siRNA or Accell Non-targeting siRNA #1 in Accell delivery media. Reduction of eGFP expression is visualized using Cellomics ArrayScan VTI (green= GFP expression; blue= nuclear Hoechst dye).

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 References tab for a list of publications.

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.
