"If you have access to a real-time PCR instrument, you can use PCR Arrays"

RT² Profiler™ PCR Arrays are the most reliable and sensitive gene expression profiling technology for analyzing a panel of genes in signal transduction pathways, biological process or disease related gene networks. The PCR Arrays can be used for research on cancer, immunology, stem cells, toxicology, biomarker discovery and validation, and phenotypic analysis of cells and transgenic animals. See the complete list of PCR Arrays.

You can use any 96-well or 384-well real-time PCR instrument. See instrument-specific setup instructions. Click below for detailed information.

How it Works

The PCR Arrays are sets of optimized real-time PCR primer assays on 96-well plate, 384-well plate, or 100-well disc for pathway or disease focused genes as well as appropriate RNA quality controls. The PCR array performs gene expression analysis with real-time PCR sensitivity and the multi-gene profiling capability of a microarray. Simply mix your cDNA template with the appropriate ready-to-use PCR master mix, aliquot equal volumes to each well of the same PCR Array, and then run the real-time PCR cycling program.

How Biomarker signature genes were developed

RT� Predictor PCR arrays have the capability to measure pathway activity based on target gene expression changes using SYBR Green real-time PCR technology. The algorithm developed along with individual RT� Predictor PCR array will measure pathway activity based on selected target gene expression changes and provide a single score of pathway activity readout to customer.

The target genes (Biomarker Signature genes) that will be used to measure pathway activity are experimentally derived and verified. These Biomarker Signature genes and companion algorithm are derived from a training data set consisting of 10-15 different cell lines whose pathway activity are either activated or inhibited with experimentally verified methods. The general workflow for Biomarker Signature gene development is illustrated below.



Development of Biomarker Signature genes for pathway activity determination

Development of Biomarker Signature genes for cellular toxicity determination

Pathway activity score:

Our unique algorithms use Ct values generated from the biomarker signature genes to generate the pathway activity score.

A 1

B 1

Interpretation of pathway activity score. (A) Signal transduction pathway activity. Positive score indicates stimulation of pathway activity while negative score indicates repression of pathway activity. * Samples with P value <0.05 as well as probability score >0.3 or <-0.3 indicate significant pathway activity change in an experimental sample compared to a control sample. (B) Cellular toxicity levels. *Samples with P value <0.05 and probability score >0.3 indicate significant toxicity level change in an experimental sample compared to a control sample.

Performance Data Sensitivity:
The complete PCR Array System yields a greater-than 85 percent present call with as little as 25 ng for gene expression profiling and as much as 5 �g of total RNA from a pathway representing genes expressed at a lower level.

Figure 2:

PCR Arrays Let You See More Genes with Less RNA
Different amounts of universal total RNA were characterized using QIAGEN�s PCR Array, and the percentage of detectable genes was calculated for each RNA amount.
As little as 25 ng total RNA yields greater than an 80% positive call.


The complete PCR Array System demonstrates strong correlations across technical replicates, lots, and instruments with average correlation coefficients > 0.99 insuring reliable detection of differences in expression between biological samples.

PCR Arrays Yield Highly Reproducible Results
Four replicate sets of raw threshold data (1-4) obtained by two different scientists (A & B) at two different times (050825 & 060111) on Mouse Drug Metabolism RT² Profiler™ PCR Arrays are directly compared. The results demonstrate a high degree of correlation (R2 > 0.990).


The complete PCR Array System, with high quality input RNA, is guaranteed to yield single bands of the predicted size without primer dimers or other secondary products thus providing the most accurate real-time PCR results possible.

Universal total RNA was characterized on the TGF� / BMP Signaling Pathway PCR Array, followed by dissociation (melt) curve analysis. PCR Arrays specifically detect individual genes despite the expression of related gene family members in the same RNA sample.


Application Example

RT² Profiler™ PCR Arrays can be used in all areas of life science and biomedical research including:

  • Cancer
  • Inflammation and cytokine profiling
  • Stem cells
  • Neuroscience
  • Cell development
  • Signal transduction pathways
  • Biomarker screening and validation

We list below an example of application data generated by our R&D group. < /p>

Benefit of coupling gene profiling with activity determination

Mouse embryonic colon epithelial FHC cells were treated with WNT3a ligand for 3h. Western blot analysis (A) indicated activation of WNT/b-catenin pathway activity while whole genome microarray study (B) suggested no change after Wnt3a treatment.

1     1



To explain this discrepancy, RT² Profiler WNT Signaling PCR Array was used to exam pathway activity of and gene expression changes in the WNT/b-catenin pathway. Pathway activity score indicated no change in pathway activity in FHC cells after WNT3a treatment (C)




However, Gene expression profiling indicated upregulation of AXIN2, a negative regulator of WNT signaling, in FHC cells upon WNT3a treatment (D), suggesting a negative feedback mechanism to suppress pathway activity in FHC cells after WNT3a stimulation.




Cross Validation

The utility of the 16 Wnt/β-catenin signature genes was verified by cross validation with a Random Forest classification method and more than 80% of treatment samples were classified correctly based on this 16 gene signature, as shown below. Stimulated samples, different cell lines with pathway activity stimulated. Repressed samples, different cell lines with pathway activity repressed. Control samples, different cell lines without treatment.
