Ambion™ Silencer™ Select Negative Control siRNA, In Vivo Ready is extensively validated and an ideal control for many aspects of an siRNA experiment. The control is highly purified as required for animal use. 250 nmol is provided.• Premium-quality siRNA, highly purified and ready to use• Functionally tested in several common cell lines• Include Silencer™ Select modifications for enhanced specificity• For use in human, mouse, and rat cellsWhat are Silencer™ Select siRNAs?Silencer™ Select 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. The result is fewer failed experiments due to poor silencing, and cleaner, more consistent phenotypic data.Silencer™ Select GAPDH Positive Control siRNA:The Silencer™ SelectGAPDH positive control is extensively validated and an ideal “test” siRNA for those just beginning siRNA experiments, because it is validated to work in multiple cell lines. Because it targets GAPDH mRNA (a common internal control), many assays are available to measure its effects, including real-time RT-PCR as well as the Ambion™ KDalert™ GAPDH Assay Kit.Quality Control:Silencer™ Select siRNAs are manufactured in a state-of-the-art facility under the highest quality standards. Rigorous quality control procedures include MALDI-TOF mass spectrometry analysis and analytical HPLC to monitor purity. Each siRNA is also assessed by gel electrophoresis to confirm that the strands anneal properly. Furthermore, In Vivo Ready siRNAs undergo additional purification with a semipermeable membrane to remove excess salt. This is followed by sterile filtratation and endotoxin testing. At concentrations of 50 μM in deionized water, In Vivo Ready siRNAs contain. less than 0.6 mM Na^+, less than 2.0 mM K^+, and less than 0.1 mM Mg^2+. Silencer™ Select siRNA controls have specific chemical modifications; they are designed to be used with Silencer™ Select siRNAs. If you are using other siRNA products, such as BLOCK-iT™ siRNAs, Ambion™ Silencer™ siRNAs, or STEALTH RNAi™ siRNAs, we recommend that you use control siRNAs designed for use with those siRNAs for more reliable experimental results.
