Small interfering RNA/silencing RNA (siRNA) is a class of double-stranded, non-coding RNA molecule, 20-25 base pairs in length. As part of the RNA interference pathway, it regulates gene expression by degrading mRNA after transcription, preventing translation.
Silencer™ Select siRNAs are classic 21-mers which incorporate the latest improvements in siRNA design, off-target effect prediction algorithms, and chemistry.
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.
Silencer™ custom siRNAs (unmodified 21-bp duplexes) are cost-effective RNA interference (RNAi) tools ideal for knocking down gene expression in order to study protein function in a wide range of cell types.
These siRNA collections enable medium and high throughput analysis of phenotypes resulting from inhibition of large sets of targets from specific functional classes.
Ambion™ Silencer™ SelectGAPDH Positive Control siRNA, In Vivo Ready is extensively validated and an ideal control for many aspects of an siRNA experiment.
