Multicolor FISH (M-FISH) Analysis


Multicolor FISH (M-FISH) assays are used for a precise assessment of complex chromosomal rearrangements. This technique uses all whole-chromosome painting probes in multiplex-FISH and spectral karyotyping. Thus, marker chromosomes, complex chromosomal rearrangements, and all numerical aberrations can be visualized simultaneously in a single hybridization experiment. M-FISH is a kind of versatile tool for precise chromosome separation and for rapid chromosome classification help speeding up the workflow. Apart from that, the analysis of M-FISH images is easy even if aberrations are involved.

M-FISH complements the standard cytogenetic methods, which is helpful in deciphering complex chromosomal rearrangements and is used to identify non-random structural chromosome rearrangements not detectable by other methods. Genomic alteration of many tumor cell lines was characterized by M-FISH.

Our M-FISH has unparalleled advantages:

  • Rapid analysis of metaphase spread
  • Ability to analyze complex cases with multiple chromosomal rearrangements, identification of marker chromosomes
  • Ability to distinguish different imbalanced situations detectable in aCGH
  • Ability to accurately karyotype single metaphases without selection


  • High accuracy and sensitively
  • Fast turnaround time
  • Competitive pricing
