Interpretation of Ct values- Fold change calculations: PCR Array results / data

Raw Ct Value: Relative expression level of that gene in the sample1

Up or down-regulation= ∆∆Ct per Gene = ∆Ct

Condition 2 - ∆Ct Condition 1

Fold change results per gene = 2-∆∆Ct

Data normalization = ∆Ct per Gene = Ct Gene X - Ct HKGs (Avg)

Ex. My gene is present 4X more in the treated sample than in control sample.Now not only gene, but GENES in a Pathway (some up, some down)

Sample & Assay Technologies

Technical• Not necessary Save time & money• Reproducibility of the PCR Arrays is very high• Results demonstrate that what you are seeing is a result of

biology, not technique• RTC & PPC show technical reproducibility on each plate, and

comparable across plates.

Biological• Needed to verify the results are a result of biology • At least 3 replicates per condition for statistical analysis

-> p values
