Human Multicolor FISH Probe

Order Number
Package Size
(6 Tests)



24 painting probes specific for the 24 different human chromosomes, labeled with different fluorochromes. The excitation/emission spectra are comparable to the common aqua, green, orange, red and near infrared fluorochromes.

Also available as 120µl (2x60µl) D-0125-120-DI and as 600µl (10x60µl) D-0125-600-DI.

Probe maps are created in accordance with the intended purpose of the product. Solid colored bars do not necessarily indicate that the probe fully covers the indicated genomic region. Therefore, caution is advised when interpreting results generated through off-label use. Probe map details based on UCSC Genome Browser GRCh37/hg19. Map components not to scale. Further information is available on request.

Clinical Details

The principle of mFISH is based on combinatorial labeling of whole chromosome paints. For each chromosome the different fluorochromes are mixed resulting in a unique color combination (see labeling scheme). The analysis is carried out after capturing grey scale images of each fluorochrome. For best separation of the different colors, the filter sets used need to be highly selective, assuring that crosstalk is reduced to a minimum. Multicolor FISH Analysis with MetaSystems‘ Isis supports the analysis by applying appropriate algorithms which leads to pseudo coloring of the different chromosome classes (color combinations). Each chromosome class will be displayed in a unique color. Translocations show up as color changes on individual chromosomes.
