Pre-defined Silencer Select siRNA libraries

These libraries have been pre-assembled using PANTHER (www.pantherdb.org ) and Gene Ontology™ annotation information to create up-to-date target gene sets.

Each gene is targeted by three unique siRNAs. Validated siRNAs are included at no extra cost.
0.25 nmol of each siRNA is provided dried-down in the wells of barcoded 96- or 384-well plates. This is sufficient for 100-500+ transfections, depending on siRNA working concentration and reaction volume.
Column 12 of each 96-well plate and columns 23 and 24 in each 384-well plate are left empty to allow for the addition of controls at the time of use.
Plates are conveniently arranged for pooling of siRNA, if desired.
The libraries are delivered with plate map files including full siRNA sequence information, as well as each targeted gene's symbol, full name, aliases, RefSeq accession, and Entrez Gene ID.
