Descrizione

Silencer™ siRNA Libraries feature combinations of Silencer Pre-designed siRNAs, and when available, Silencer Validated siRNAs, in 96-well or 384-well plates. The design of each siRNA has been optimized for potent and specific silencing. The siRNA selection process yields siRNAs that are effective at low concentrations, enabling screening experiments at 30 nM siRNA or lower, minimizing reagent costs and off-target effects.

To ensure specificity, the siRNA design algorithm incorporates a rigorous check of all siRNA sequences. This process is accomplished via a modified alignment search tool that effectively identifies short regions of sequence alignment that BLAST searches miss. Sequences that have significant regions of similarity to off-target transcripts, fall in polymorphic regions (e.g., SNPs), or if they are predicted to invoke an antiviral response are eliminated. In addition, the siRNA design process incorporates stringent rules to prevent off-strand targeting.

Effective—siRNAs meticulously designed for potency and specificity

Convenient—ready-to-use siRNAs in amounts sufficient for hundreds of transfections

Reliable—three siRNAs per target increase screening accuracy, ideal for pathway analysis, target identification, and validation

Comprehensive—available for small gene sets and for the whole human genome

Customizable—custom aliquotting, pooling, and custom libraries available

Guarantee for Silencer™ Pre-designed siRNAs
Life Technologies guarantees that when you purchase three Silencer Pre−designed siRNAs to the same target, at least two of the siRNAs will reduce target mRNA levels in cultured cells by 70% or more when measured 48 hours after transfection at 100 nM or higher final siRNA concentration under the conditions described below. If atleast two of the three siRNAs do not induce >70% target mRNA knockdown, Life Technologies will provide a one−time replacement of up to three Silencer Pre−designed siRNAs per target at no additional charge. Requests for replacement product must be made within one hundred and eighty (180) days from the date of delivery of the Silencer Pre−designed siRNAs. Optimum transfection efficiency must be confirmed using good laboratory practices and a proven−to−work siRNA to an endogenous message, such as Ambion Silencer GAPDH siRNA Control. To assess knockdown, target mRNA levels in treated samples must be compared to that of cells transfected with a nontargeting control siRNA, such as Silencer Negative Control #1. We recommend Applied Biosystems TaqMan™ Gene Expression Assays to quantify mRNA levels.

Specifica

• Content And Storage: Silencer™ Select siRNAs are the result of recent improvements in siRNA design combined with novel chemical modifications yielding unrivaled knockdown efficiency and specificity. Our best performing siRNA for cell culture work. Silencer™ siRNAs are unmodified 21 nucleotide siRNAs that have been designed with an older, yet rigorously tested design algorithm. A lower cost alternative to Silencer™ Select siRNAs, but without some of the performance enhancements.
