Transcription factors are fast becoming promising drug targets, as they bind to and regulate the transcription of genes. The Silencer Human Transcription Factor siRNA Library targets genes expressing proteins that bind DNA in a sequence-specific manner to control the rate of transcription of genetic information from DNA to messenger RNA. The Silencer™ Human Transcription Factor siRNA Library contains a total of 5,583 Ambion™ Silencer siRNAs targeting 1,861 genes. The library was designed using the most up-to-date genome databases, including the NCBI RefSeq database and cross-referenced to the Gene Ontology Consortium (GO) database and/or the HUGO Gene Nomenclature Committee (HGNC). Utilizing Ambion Silencer technology built on stringent bioinformatics to ensure high target specificity and siRNA potency, the Silencer Human Transcription Factor siRNA Library is an ideal solution for focused and cost-effective transcription factor RNAi screening.

Why use the Silencer Human Transcription Factor siRNA Library?
Together with careful bioinformatics selection of gene targets, Silencer siRNAs are optimized for design and high quality synthesis with guaranteed silencing (learn more about the guarantee). The Silencer Human Transcription Factor siRNA Library contains our pre-designed and when available, validated siRNAs generated with maximum potency and specificity in mind so you can focus on data quality (learn more about the design). All Silencer libraries are selected against the latest available databases and resources for up-to-date content. Full siRNA sequence information, as well as the exon targeted and each targeted gene's symbol, full name, aliases, RefSeq number, and Locus ID, plus results from any validation experiments performed using the included siRNAs is provided. Please contact us for the complete list of targets.

Silencer siRNA libraries allow you to screen efficiently and maximize data output
Ambion Silencer siRNAs are designed with potency in mind to help ensure gene knockdown at minimum concentrations. This not only helps ensure less potential for off target effects and false positive data but also minimizes false negative outcomes of siRNA screening. The Silencer Human Transcription Factor siRNA Library contains 0.25 nmol of each siRNA, sufficient for 100 transfections (at 25 nM siRNA, 100 μL transfection volume).

Flexibility to meet your workflow needs
Thermo Fisher Scientific offers comprehensive list of pre-defined or custom siRNA libraries to human, mouse or rat genes with 1, 2, or 5 nmol of each siRNA or larger sizes.
