SATQPCR is a web tool providing statistical analysis of real-time quantitative PCR data including all MIQE rules (gene efficiency, selection of reference genes and normalization with them). There are broad groups of statistical tests, parametric and non-parametric. The analysis of variance (ANOVA) can be used to compare treatments using the previously calculated quantification results. It splits an observed aggregate variability that is found inside the data set. Recent studies have proposed the use of at least three different methods but there is no consensus on how to interpret conflicting results. Multiple statistical approaches have been proposed to validate reference genes in qPCR assays. A SAS program to perform Ct analysis using ANOVA methodology is provided in Appendix 2. For the cDNA dilution analysis, linear regression modeling was used. However, it can only be used when certain criteria are met. qRT-PCR technology is now one of the commonly used methods to study gene expression levels. CT was calculated by the difference between the CT values of the BCL2, p53 and the CT value of B-actin gene.. The selection of accurate reference gene detection is an essential work before gene expressing analysis. Our web-application will provide a quick tool (few seconds) to the biologists in order to analyze RT-qPCR data for any set of samples including technical and biological replicates using MIQE rules and statistical tests. Please refer the lecture notes to make sure that these criteria are fulfilled.
