2157 unique siRNAs targeting each of 719 kinase genes
Total of 27 96-well plates (plates are Axygen #PCR96FS;
24 plates with 88 siRNAs each
3 plates with 15 siRNAs each
See accompanying CD for sequence information and additional siRNA details.




Store at or below 鈥?20掳C. Do not store in a frost-free freezer. (Dried oligonucleotides are shipped at
ambient temperature.)

1 year, when stored at or below 鈥?20掳C.
Shelf Life:


The mass of a sample of each single-stranded RNA oligonucleotide is analyzed using MALDI-TOF mass
spectrometry and compared to the calculated mass.

A sample of the annealed siRNA is analyzed by nondenaturing gel electrophoresis.


Silencer Human Kinase siRNA Library V3 targets 719 human kinases with three individual siRNAs per
Product Description:
gene. These chemically synthesized siRNAs are 21-mers comprised of 19 bp dsRNA molecules with
dinucleotide 3' DNA overhangs. The sequences of the siRNAs (provided in the accompanying CD) were
designed using a proprietary siRNA design algorithm that results in highly efficacious and specific siRNAs.

Handling Instructions:
handling. Wear gloves when handling this product. Use RNase-free reagents, tubes, and barrier pipette tips.
Upon receipt, your siRNAs may be safely stored in a non-frost-free freezer at or below 鈥?20掳C (dried
oligonucleotides are shipped at ambient temperature).

Resuspension of siRNAs
Centrifuge each plate at low speed (maximum RCF 4,000 X g) to collect the contents at the bottom of the
wells before removing the seal in step 1.

Important: Perform this process under a tissue culture hood.

1. Remove seal carefully.
2. Add 50 碌L nuclease-free, sterile, water using a multichannel pipette and sterile tips (adding 50 碌L
water to 0.25 nmol siRNA will make a 5 碌M stock*).
3. Gently pipette up and down 5 times to resuspend.
4. (Optional) Aliquot the siRNAs into one or more daughter plates, to limit the number of freeze-thaw
cycles to which the siRNAs are subjected.
5. Place a new sterile seal (such as Axygen PCR-AS-200) on the plate before storing.
6. Store at 鈥?80掳C until ready to use.

Applications: Transfecting siRNAs Into Mammalian Cells
The efficiency with which mammalian cells are transfected with siRNA will vary according to cell type and the
transfection agent used. This means that the optimal concentration used for transfections should be
determined empirically. We have found that siRNAs typically work best when present in cell culture medium
at 10鈥?50 nM; however, a more extensive concentration range from 1鈥?100 nM can be analyzed in
optimization experiments.

Final Volume per Well
Refer to the instructions provided with your transfection agent for the recommended volume.
The siRNA amount shown results in a final siRNA concentration of 30 nM. The amount of siRNA required for maximal gene
silencing will vary from cell type to cell type. For a 96-well plate, and a 100 碌L final transfection volume, 3 pmol of a 5 碌M siRNA
solution is 0.6 碌L. Robotic pipettors may require volumes of 2鈥?5 碌L for accurate pipetting. To increase pipetting volumes and
accuracy, we recommend preparing a plate with a dilution of your stock siRNA when preparing transfection complexes.
Optimal cell density will vary from cell type to cell type, depending on cell size and growth characteristics. In general, 30鈥?70%
confluency is recommended.

Transfection Optimization
Optimizing transfection efficiency is crucial for maximizing gene silencing while minimizing cytotoxicity.
Optimal transfection efficiencies are achieved by identifying an effective transfection agent for each cell type
and by adjusting (in order of importance):
鈥? Amount of transfection agent
鈥? Amount of siRNA
鈥? Cell density at the time of transfection
鈥? Order of transfection (pre-plating cells or plating cells/transfecting in tandem)
鈥? Length of exposure of cells to transfection agent/siRNA complexes

Most protocols recommend maintaining mammalian cells in the medium used for transfection; this avoids
diluting or removing the siRNAs from the cells by adding medium or washing the cells with new medium too
soon after transfection. We have found that cells typically exhibit greater viability when existing medium is
replaced by fresh medium 24 hours after transfection. Replacing medium after 24 hours generally does not
change the activity of the transfected siRNAs.

Once the conditions for maximal gene silencing are determined, they should be kept constant from
experiment to experiment for a given cell type. Include controls in all plates for each experiment to ensure
