• Up to 100 fold more potent than currently available siRNAs
• Demonstrated improvements in consistency and reliability of phenotypic results

What are Silencer™ Select siRNAs?

Silencer™ Select siRNAs are the next generation Ambion™ siRNAs. These siRNAs incorporate the latest improvements in siRNA design, off-target effect prediction algorithms, and chemical modifications to yield siRNAs with unrivalled efficacy, potency, and specificity. In siRNA screening applications, the result is fewer false negatives due to poor silencing and fewer false positives due to off target effects. In other words, with Silencer™ Select siRNAs you get cleaner, more consistent data from your primary screen, so you expend less time and resources to find true, validated targets. The result is fewer failed experiments due to poor silencing, and cleaner, more consistent phenotypic data.

Human Genome siRNA Library (Comprised of Cat. No. 4397922, 4397923, and 4397924)

Increasingly, researchers are performing genome scale surveys of gene function. The Silencer™ Select Human Genome siRNA Library V4 is ideal for this purpose. Three unique, non-overlapping siRNAs are provided for each of 21,584 human targets. The siRNAs targeting the 'druggable' portion of this library are arranged by gene functional class to enable easy screening of important gene subsets such as kinase, phosphatase, GPCR, etc. This siRNA library is supplied in 384-well plates.

Human Druggable Genome and Human Extended Druggable Genome siRNA Libraries

With siRNAs targeting the most therapeutically relevant human genes and conveniently grouped by target gene class, the Silencer™ Select Human Druggable Genome siRNA Library V4 and Silencer™ Select Human Extended Druggable Genome siRNA Library V4 are popular choices for many researchers. The druggable genome set targets 9031 genes, whereas the extended druggable genome collection targets those genes plus the 'Extension Set' for a total of 10414 genes, including transcription factors. Please contact us for the complete list of targets. These libraries are available in both 96- and 384-well plate formats.

Human Kinase siRNA Library

Because of their importance in cell signaling and many biological pathways, kinases are key drug targets and subjects of intense scrutiny. The Silencer™ Select Human Kinase siRNA Library V4 targets 710 human kinases with three individual Silencer™ Select siRNAs per gene. This siRNA library enables systematic, yet cost effective, RNAi studies of these key cell regulators. Validated siRNAs are included where available. The Silencer™ Select Human Kinase siRNA Library V4 is provided in 96-well plates.

Human Phosphatase siRNA Library

Along with kinases, phosphatases are important regulators of biological pathways and cell signaling cascades. The Silencer™ Select Human Phosphatase siRNA Library V4 targets 298 human phosphatases with three individual siRNAs per gene supplied in 96-well plates. This library is the ideal companion to the Silencer™ Select Kinase siRNA Library V4, enabling more detailed studies of biological pathways.

Human GPCR siRNA Library

G protein-coupled receptors, or GPCRs, are key components of many signal transduction pathways and also represent an important class of druggable genes. The Silencer™ Select Human GPCR siRNA Library V4 targets 379 non-olfactory human GPCRs with three individual Silencer™ Select siRNAs per target supplied in 96-well plates.

Human Protease, Nuclear Hormone Receptor, and Ion Channel siRNA Libraries

Focused siRNA sets to human proteases, ion channels, and nuclear hormone receptors provide a cost effective means of studying these important regulators of cellular function. These siRNA libraries are each supplied in 96-well plates. The Silencer™ Select Human Protease siRNA Library V4 features 3 siRNAs per target for 494 human proteases. The Silencer™ Select Human Nuclear Hormone Receptor siRNA Library V4 includes 3 siRNAs per target for 47 nuclear hormone receptors. The Silencer™ Select Human Ion Channel siRNA Library V4 features 3 siRNAs per target for 338 human ion channels.

Individual siRNAs for Enhanced Data Reliability

Silencer™ Select siRNA Libraries feature three individual siRNAs for each target. Screening with three siRNAs per gene significantly decreases both false positive and false negative rates, resulting in enhanced confidence in RNAi screening data, reduced chance of missing important genes, and less time spent following up on false positive hits from the screen.

These libraries contain 0.25 nmol of each siRNA, sufficient for 500 transfections (at 5 nM siRNA, 100 μL transfection volume). The siRNAs are supplied dried into the wells of 96 well plates. One column of each 96 well plate is left empty to allow for the addition of controls at the time of use. The libraries are delivered with full siRNA sequence information, as well as the exon targeted and each targeted gene's symbol, full name, aliases, RefSeq number, and Entrez Gene ID, plus results from any validation experiments done using the included siRNAs.

Silencer™ Select siRNA Libraries to these or any other list of human genes can also be provided with 1, 2, or 5 nmol of each siRNA. Custom formatting is available with these larger sizes.
