How do I calculate the percentage of silencing with real-time RT-PCR for siRNA?

Two different FlexiTube products are available: FlexiTube siRNA and FlexiTube GeneSolution. FlexiTube siRNA is a cost-effective solution for RNAi analysis of small numbers of genes. siRNAs are provided in 5 nmol or 20 nmol amounts for human, mouse, or rat genes, or in economical 1 nmol amounts for human and mouse genes. FlexiTube GeneSolution is a gene-specific package of 4 preselected siRNAs (1 nmol) for a target gene. FlexiTube GeneSolutions enable researchers to use multiple siRNAs for each target ensuring reliable results. FlexiTube siRNA and FlexiTube GeneSolutions are designed using innovative HP OnGuard siRNA Design and are available at QIAGEN's GeneGlobe Web portal.

HP Custom siRNA is an siRNA synthesis option that provides for specific siRNA requirements, including siRNA for multiple species, specific splice variants, and non-human, -mouse, and -rat genes. HP Custom siRNA provides highly pure siRNA in 20 nmol amounts. Available fluorescent labels include Alexa Fluor 488, Alexa Fluor 546, Alexa Fluor 555, Alexa Fluor 647, Cyanine 570, Cyanine 670, fluorescein, and rhodamine dyes. Modification options include amino linkers, thio linkers, and biotin, dabcyl, and phosphate modifications.
