Gene Expression Analysis

Expression Profiling using Thermo Fisher (previously Affymetrix) microarrays.

The Facility of Microarray Analysis offers expression analysis services including Whole Transcript (WT) Expression arrays ( Clariom D arrays, Clariom S arrays, gene arrays), 3′ Expression arrays and miRNA arrays.  Submitted for expression analysis RNA samples undergoes a mandatory quality and quantity assessment using the Agilent Bioanalyzer.

For the analysis of human, rat and mouse transcriptome at the gene-level detection our Facility recommends using Clariom S and for both the gene-level and the identification of known transcript isoforms we recommend Clariom D assays. These assays provide a substantial amount of information at a favorable cost.

Clariom D arrays:

  • offer an exceptionally in-depth analysis of the transcriptome, examining over 540 000 transcripts, providing the fastest route to actionable results from as little as 100 pg of total RNA
  • enable translational research specialists to quickly and easily create highly accurate biomarker profiles
  • provide highly sophisticated understanding of gene and exon expression at the transcriptome level, including the capability to detect alternative splicing events in both coding and long non-coding (lnc) RNA, all within a single three-day experiment
  • stands as the most comprehensive among whole-transcript expression arrays, specializing in profiling the transcriptomes of humans, mice, and rats
  • offers the necessary coverage and precision required for identifying all known transcript isoforms originating from a single gene.

The Clariom S assay offers a targeted analysis of gene-level expression within a transcriptome focused on 20,000 best-annotated genes, making them suitable for various clinical sample types. Clariom S Assays are the preferred tools for efficiently and affordably discovering expression biomarkers with well-defined functions.

Clariom S and Clariom D assays:

  • Create reliable expression profiles from just 100 pg of total RNA
  • Utilize total RNA from diverse sample sources such as whole blood, cultured cells and fresh/fresh-frozen or formalin fixed, paraffin-embedded (FFPE) tissues
  • Maintain sample integrity and minimize data fluctuations using an assay not requiring a globin or rRNA removal.



DNA methylation profiling at the single-CpG-site level using Illumina Infinium MethylationEPIC BeadChips.

The Facility of Microarray Analysis offers Illumina methylation BeadArray technology.

Aberrant DNA methylation pattern results in the deregulation of gene expression and has been implicated in numerous cancers. With the Illumina Human MethylationEPIC Array you can not only perform epigenome-wide association studies but also identify differentially methylated sites in tumor versus normal tissues.

Now available the newest Infinium MethylationEPIC v2.0 Array – an enhanced version of the EPIC v1.0 representing Illumina’s state-of-the-art approach for genome-wide DNA methylation analysis, leveraging bisulfite conversion. This advanced technique facilitates the precise quantification of the overall methylation status at more than 930,000 individual methylation sites across the human genome, down to single nucleotide resolution. It provides extensive coverage of critical regions in the methylome, including CpG islands, enhancer regions, open chromatin sites, and other significant genomic areas, featuring expanded content in comparison to the EPIC v1.0.

Infinium MethylationEPIC v2.0 Array covers the following content areas:

  • Expanded coverage of CpG islands
  • Enhanced exon coverage for more accurate copy number variation (CNV) detection
  • Non-CpG (CHH) methylated sites identified in human stem cells sites
  • ENCODE open chromatin and enhancers
  • FANTOM5 enhancers
  • DNase hypersensitivity sites
  • miRNA promoter regions
  • Enhancers and super-enhancers identified by ChIP-Seq in cancer and cell line samples Differentially methylated sites identified in tumor versus normal samples for multiple cancers
  • Differentially accessible chromatin regions identified in primary human cancers using ATAC-Seq
  • Common cancer driver mutations
  • > 85% HumanMethylation450 BeadChip content


RNA/DNA analysis using Bioanalyzer

Quality and quantity verification of RNA or DNA samples for any downstream application, analysis using Agilent Bioanalyzer is available.


qPCR analysis

The Facility of Microarray Analysis offers Realtime PCR analysis, both qualitative and quantitative of DNA and RNA samples, using Roche LightCycler 480 Instrument.
The service offered includes primer design for selected matrices, optimization of the assay, verification of RNA purity, if applicable, and Realtime PCR analysis. Preliminary quantitative analysis of the data is also available.


GeneChip®Scanner 3000 Targeted Genotyping System (Affymetrix) including the GeneChip Scanner 3000 7G with AutoLoader, two Fluidics Stations 450, Hybridization Oven 645 and Affymetrix GeneChip Command Console Software (AGCC). This system enables transcriptomic analysis using Clariom S and Clariom D arrays, interrogation of miRNA composition with dedicated GeneChip arrays as well as High Resolution Chromosome Copy Number Analysis Using GeneChip Mapping Arrays.

The HiScanSQ system (Illumina) facilitated epigenetic analysis with Infinium MethylationEPIC v2.0 Array

LightCycler-480 Roche – a high-performance PCR platform that delivers methods for gene detection, gene expression analysis, genetic variation analysis and array data validation.

Bioruptor® Plus sonication device (Diagenode) used for chromatin fragmentation, a preliminary and necessary step to obtain starting material for preparing libraries for analysis using ChiP-seq next-generation sequencing.

2100 Bioanalyzer (Agilent) used for the control of quality nucleic acids samples. It uses capillary electrophoresis technique and allows up to 12 samples to be analyzed in parallel. The device allows to evaluate the quality of both DNA and RNA, before and during the microarray analysis steps, as well as to assess the quality of the performed libraries for next-generation sequencing.

The NanoDrop ND-1000 spectrophotometer allows measuring the absorbance of nucleic acids in 1 µl volume, with high accuracy and reproducibility, over a wide range of concentrations (2-3700 ng/ µl for double-stranded DNA).

MagNa Lyser Instrument (Roche Diagnostics) a homogenization module allows automated fragmentation of tissues and consequent disintegration of cells of various origins.

MagNA Pure Compact Instrument (Roche Diagnostics) enables isolation of DNA or RNA simultaneously from eight samples and provides guarantees of safety in working with human material and excludes the possibility of contamination of samples, while ensuring high reproducibility of isolation performance.
