Methodological study demonstrates group-wise relative gene expression analysis in real-time PCR assays, highlighting improved statistical evaluation of multi-sample transcript quantification.

Key Points

To develop and describe a software tool (REST) capable of group-wise comparison and statistical significance testing of relative gene expression ratios in real-time PCR.
Formulated a mathematical model based on real-time PCR efficiencies and mean crossing point (CP) deviations between sample and control groups.
Programmed the Relative Expression Software Tool (REST) to process up to 16 data points per sample group and 16 per control group across a reference gene and up to four target genes.
Integrated a statistical randomisation test to determine the significance of calculated expression ratios between groups.
Expanded relative gene expression analysis from pairwise single-sample comparisons to group-wise comparisons of up to 16 samples per group.
Enabled simultaneous normalization of up to four target transcripts against a non-regulated reference gene with automated randomisation testing.
