Thermo Fisher, AM1780, ArrayControl™ RNA Spikes

Quantity: 8 Tubes
Unit Size: Each
When hybridized to complementary spots on a gene array, ArrayControl RNA Spikes can be used to monitor the efficiency of reverse transcription and aRNA amplification, labeling, and hybridization. They can also be used to assess the precision, accuracy, and consistency of array printing and protocol sensitivity. In addition, RNA Spikes are an invaluable tool for protocol optimization and troubleshooting. They can be used for normalization of Cy3 and Cy5 signals, determination of dynamic range, and slide orientation. Individual RNA Spikes can also be omitted to serve as a negative control for background calculations. The RNA Spike sequences have been carefully chosen to lack homology to mammalian sequences that might otherwise lead to cross-hybridization to gene-specific spots. Each RNA Spike is purified, precisely quantitated by spectrophotometry and RiboGreen™ staining, and tested for stability under highly stringent conditions. They are also tested for cDNA labeling efficiency using both direct and indirect methods. Their manufacturing and quantitation are consistent from lot-to-lot, so that signals can be compared between experiments and to assess array reproducibility.
