Genome-Wide Plasmid-Based RNA Interference

The SureSilencing™ Pre-Designed shRNA Plasmids specifically knock down the expression of every human, mouse or rat gene by RNA interference. For each gene, we provide four plasmids each with a different pre-designed short hairpin RNA (shRNA) sequence. Our proprietary experimentally verified shRNA design algorithm insures the maximum gene-specificity and efficacy. At least two of the four pre-designed shRNA plasmids are guaranteed* to knock down expression of the targeted gene. The availability of two effective sequences allows you to properly control for non-specific and off-target effects.

Human                      Mouse                      Rat
Gene Name:       RefSeq No.:      Unigene No.:      

Enrich or Select: Plasmids are available with either GFP Marker or Hygromycin, Neomycin, or Puromycin Resistance, enabling enrichment and the study of the long-term effects of gene suppression.
GUARANTEED!*: Knock down expression of the targeted gene by at least 70 percent. Control for non-specific and off-target effects.
Convenient & Cost-Effective: Use standard plasmid-based and lipid-mediated transfection methods. Plasmids provide a renewable source of RNA Interference.

We offer four different plasmid formats for the SureSilencing™ shRNA. Plasmids containing the hygromycin, neomycin, or puromycin resistance gene let you select for stably transfected cells and study long-term effects of gene knock-down in your cells. Plasmids containing the GFP gene offer a better alternative to siRNA letting you identify and track transiently transfected cells and study short-term effects in a transient transfection. The ability to track or stably express shRNA enables you to carry our RNA interference studies in difficult-to-transfect cells.

Unlike chemically synthesized siRNA, plasmid-based shRNA provides a renewable source of RNA interference. You can amplify enough plasmid in your own lab to complete your project. Purchase of our plasmids also includes complete shRNA sequence information.
