Using a microarray technology, a wide range of applications can be serviced, where content/specificity is defined by the probes on the array. A grasp of the possible  applications :

  • Genotyping (multi-species)

  • Cytogenomics

  • Gene expression analysis

  • Methylation profiling

  • miRNA profiling

  • Pharmacogenetic testing

  • ...

With the advent of Massive Parallel Sequencing (MPS) or Next Generation Sequencing (NGS), array technologies are steadily getting abandonded, however for some applications (like methylation profiling and pharmacogenetics), they remain a - sometimes cost-beneficial - gold standard.



For the Affymetrix technology, either DNA (genotyping/CNV assays) or cRNA (expression arrays) is terminally labelled and hybridized to short probes on  a wafer. The ability of the DNA/cRNA to hybridize to the specific probes correlates to the presence of the transcript, DNA target or SNV. Signal intensities are analyzed to quantify abundance of the target of interest.

The Illumina Infinium technology is based on the hybridization of DNA (target of interest) to bead-linked probes (1 type of probe per bead), where the beads on its turn are deposited in wells on a silica slide (1 bead/well).  Following successful hybridization of the target DNA to the probe, a single base extension of the probe is performed. As this base is labelled with either biotin (C and G) or dinitrophenyl (A and T), they can be stained differentially with a fluorescently labelled antibody for either biotin or dinitrophenyl. There are 2 types of probes, (1) the Infinium I probe where the last base of the probe overlaps with the SNV of interest and (2) the Infinium II probe where the last base of this probe is 1 base before the SNV of interest. So in case of the Infinium II probes, there will always be a signal, where the detected color correlates to the SNV. For the Infinium I probe, there will only be a color signal if the last base of the probe matches with the target of interest.

The principle of the Illumina Infinium technology is depicted in the movie below.

Basic principle of the Illumina Infinium technology



The following array devices are present in our premises.

Affymetrix GeneChip 3000

Medium throughput SNP array device, where 48 samples (1 sample/genechip) can be processed simultaneously per run.

Illumina iScan

Medium throughput SNP array device, where 4 beadchips can be scanned/loaded simultaneously. The amount of samples that can be loaded is dependent on the assay/beadchip.



The specifications are subdivided in 2 sections : (1) the assay metrics and (2) applications & remarks.

More information can be found on the supplier page through the corresponding buttons in the 'Assay metrics' section.

Applications (in use)


Affymetrix GeneChip 3000

Genotyping (multi-species), Cytogenomics, Gene expression analysis, Methylation profiling, miRNA profiling

Gene expression analysis

Mainly used for expression analysis. Convenient workflow due to the automated washing and staining on the Fluidics stations and the carrousel for the automated loading of up to 48 arrays.
The flexibility of 1 sample/array is a benefit.

Illumina iScan

Genotyping (multi-species), Cytogenomics, Methylation profiling, miRNA profiling, Pharmacogenetic testing

Genotyping (multi-species), Cytogenomics, Methylation profiling, Pharmacogenetic testing

Highly used platform for Karyomapping (in context of PGT), methylation profiling and pharmacogenomics.
In order to minimize cost, the beadchips have to be fully loaded (more samples/array possible ; number of samples are array-specific).
