Concentration of Anti-Human TLR9 / CD289: Lyophilized
SiRNA Purification Method:RPC/HPLC
Storage Conditions: Store Lyophilized siRNA duplex at 4C. Reconsituted product may be stored at -20C for up to 1 month.TLR9 / CD289 Knockdown Protocol:
- Starting with cultured cells in growth media seed plates with cells and incubated at 37Â°C. The above data was generated in 6 well plates with 1.2x106 cells.
- Prepare transfection reagent in serum-free growth medium such as Opti-MEM-I. Allow to come to room temperature. Lipofectamine 2000 was used to generate the above data in accordance with manufacturerÂs instructions.</ li>
- Dilute siRNA to working concentration in serum-free growth media. For Lipofectamine or similar transfections into 6 well plates, we recommend starting siRNA dose optimization at around 150 pmol siRNA duplex.Optimal dilution should be experimentally determined.
- Combine diluted siRNA and transfection reagent. Equivalent volumes of prepared Lipofectamine 2000 or other transfection reagent and diluted siRNA should be combined and incubated at room temperature for 30 minutes with gentle mixing (optional).
- Add prepared siRNA solution to cells. For 6 well plates this will entail adding the solution to cells in approximately 2.5 ml serum-free medium. Optionally, FITC labeled control siRNA (Product Number QC-1F) or positive control siRNA (Beta-Actin; Product Number QC-2) may be used to assess transfection efficiency.
- Incubate for several hours in serum free media. The above data was generated with a 4 hour incubation.
- Add serum containing media to culture without a media change if longer incubation times are required. Generally 1-2 fold of the original volume of siRNA containing serum-free media is added to restore nutrient levels in media. Alternatively, the media may be directly supplemented with serum such as 10% FBS.
- Incubate and assay several hours after transfection. Optimal knockdown time should also be experimentally determined. Optionally, a second transfection can be performed 24 hours after the first transfection to enhance knockdown. TLR9 knockdown at the protein level was measured at 48 hours post transfection via Western Blot.
