Microarrays Unit (UM)


  • PAM

The Microarrays Unit (UM) is a service focused on DNA and RNA microarray solutions towards a personalized medicine and participates in the Cytogenetic European Quality Assessment (CEQA).

Molecular cytogenetics

Microarray studies can offer various solutions for cytogenetic applications:

  • Detection of whole genome gains and losses at a high resolution.
  • Analysis of whole genome absences of heterozygosity.
  • SNPs genotyping and genome-wide association studies.

RNA Analysis Solution

Gene expression profile studies on either human or mouse are suitable for:

  • Detection of genes and pathways involved in diseases, treatment responses and biological processes.
  • Predictive models based on gene expression profiles.
  • Pharmacogenomics and toxicogenomics studies.
  • Alternative splicing detection.
  • Classification of samples on gene signatures.
  • Analysis of miRNA.
  • Microarray analysis on compromised samples with degraded and/or low quantity samples.

Quality sample analysis

In addition, to the microarray procedure we also offer DNA and RNA quantification and quality control analysis.

High throughput qPCR – Biomark HD

-        Genotyping: Genotyping involves the analysis of single nucleotide polymorphisms (SNP) variations in genomes across individual organisms. DNA SNP genotyping on the Biomark HD Module can be performed using assays based on Fluidigm'sSNPtype chemistry or Life Technologie'sTaqMan® technology.

-        Targeted Gene Expression: Real-time quantitative PCR (qPCR) is a powerful technique for quantifying changes in gene expression by producing millions of copies of specific, targeted regions of complementary DNA (cDNA) that has been reverse transcribed from messenger RNA (mRNA) and microRNA (miRNA). Real-time qPCR on the Biomark HD Module can be performed using assays based on Fluidigm's DELTAgene chemistry or Life Technologie'sTaqMan® dual-labeled probes technology.

-        Digital PCR: Digital polymerase chain reaction (dPCR) is a technique that quantifies nucleic acid sequences that are present in a DNA sample. Digital PCR typically relies on standard PCR techniques but increases their sensitivity by dividing a sample into hundreds of smaller reactions and performing a PCR assay on eachsample. Digital PCR applications include copy number variation studies, absolute quantification,mutation detection and study of loss of heterozygosity.
