REST 2009 Software
For gene expression analysis using real-time PCR data from the Rotor-Gene Q and other cyclers Estimates up and down regulation for gene expression studies Analysis using randomization and bootstrapping techniques Graphical data output via whisker-box plots
Principle	REST 2009 Software applies a mathematic model that takes into account the different PCR efficiencies of the gene of interest and reference genes. Compared to using a single reference gene, using multiple reference genes for normalization can improve the reliability of results. Traditional relative quantitation enables estimation of gene expression. However, this method does not provide statistical information that is suitable for comparing expression in groups of treated and untreated samples in a robust manner. The integrated randomization and bootstrapping methods used in REST 2009 Software test the statistical significance of calculated expression ratios and can be used even when the data includes outliers. REST 2009 Software provides additional features for convenient and robust data analysis (see table "Convenient and robust data analysis").
Convenient and robust data analysis
Feature	Description
REST RG mode	An optional input method allows users to copy and paste results from a Rotor-Gene Q comparative quantitation analysis rather than importing standard curve and CT results.
Whisker-box plots export	Expression variation for each gene is visualized in a whisker-box plot to highlight potential issues, such as a distribution skew. Whisker-box plots are exported by right-clicking the graph.
Improved randomization	Randomization algorithms have been improved for better confidence intervals and more accurate p values.
Handling of standard curve variation	Improvements have been made to the calculation of confidence intervals and p values. Efficiency is determined using the best fit for the standard curve and is used in the randomization process.
Applications	REST 2009 Software is suitable for gene expression analysis using real-time PCR data from the Rotor-Gene Q and other cyclers.
