Constitutional Chips 4.0

Constitutional Chips 4.0 (PerkinElmer®)


Comparative Genomic Hybridization (microarray-CGH) is a technology based on detection of genomic imbalance and chromosomal aberrations (abnormalities of a few hundred kilobases up to several megabases). This technology allows quantitative analysis of genome abnormalities with a a resolution of 50 to 100 times higher than with constitutional karyotyping.
The Constitutionnal Chip 4.0 is an innovation in cytogenetics for continuous development of molecular diagnostics and research. This chip has applications in many fields and study areas, such as neonatal and prenatal diagnostics, oncology and stem cells.


Some Constitutionnal Chip 4.0 features:

  • No amplification of DNA samples is required prior to hybridization.
  • The chip offers a high resolution view of the entire genome, without pre-selection of deficient genes, unlike FISH (Fluorescent In-Situ Hybridization)
  • It provides a comprehensive coverage of clinically significant loci.
  • Cell culture is not required, unlike conventionnal karyotyping techniques.
  • This technology allows obtaining of results in less than 2 days.
