First a few quick words about the data set. We’ll be working with data coming from 3 runs (plates in the qPCR instrument): Run1, Run2 and Run3
The data consist of Cq values for:
Each is measured twice (= technical replicates) in 16 different samples. Half of the samples have undergone a treatment, half of them are untreated control samples.
The data set also contains a series of standard samples consisting of a four-fold dilution series of cDNA for each target gene. These measurements allow to generate a standard curve from which target-specific amplification efficiencies can be calculated. Finally, negative controls (No Template Controls) have been measured. The goal of the analysis is to identify target genes of interest that have different expression levels in the treated samples compared to the untreated control samples.
