Do you offer any siRNA libraries?
Yes, we have a pre-plated collection available for the entire human genome and for different functional classes as Silencer Select Libraries. We also offer custom Silencer Select library services and/or Silencer Libraries for human and mouse.

What do I do if I would like to order a fourth design of Silencer Select?
If you still would like to have 4 siRNAs in your library instead of 3, you have the option of adding 1 siRNA from our Silencer designs for the human library.

Why do your Silencer Select siRNA Libraries include 3 siRNAs, rather than 4 or more siRNAs per target?
It is generally agreed that you need at least two effective siRNA per target to confirm that a phenotype observed is due to knocking down the intended gene and not due to an off-target effect. Due to the strength of the Silencer Select siRNA design algorithm and the novel chemical modification, which serve to reduce off-target effects without negatively impacting siRNA potency, a significantly higher percentage of Silencer Select siRNAs are effective at eliciting on-target phenotypes as compared to other siRNA technologies.

What is the typical turnaround time for an Invitrogen siRNA library?
Turnaround times vary depending on the number of siRNAs and the complexity of the plating request. Most Invitrogen siRNA library orders are completed within 1-3 weeks of order processing. An estimated turnaround time for your particular library will be provided with your price quote. Please contact your local sales representative or email us at rnailibraries@lifetech.com for more information or a quote.

How should I have the siRNAs in my Invitrogen Custom siRNA Library plated?
For custom siRNA libraries, we can provide a number of plating options. Our most requested format is to have the last 1 or 2 columns empty of each 96-well plate, and to have different siRNAs to the same targets plated in separate plates in the same well location. The empty columns facilitate easy inclusion of any desired control in the final transfection plates. When different siRNAs to the same targets are plated in separate plates in the same well location, the siRNAs can easily be pooled with robotics or a multichannel pipettor. In addition, this type of format facilitates analysis by qRT-PCR.
