mFISH - CENTROMERIC AND SINGLE COPY PROBES

Basics and literature on multicolor fluorescence in situ hybridization application

 

Centromeric and single copy probes

mFISH methods can be performed using locus-specific single-copy (i.e. cosmids, P1-clones, BACs, YACs) - as mentioned above for the “chromosome bar code” . Apart from applications for special scientific approaches like the characterization of chromosomal sub-regions using mFISH on chromosome fibers (fiber-FISH) [Duell et al., 1997; Conti et al., 2007] locus-specific probes are used in some special mFISH approaches, mostly without, sometimes together with centromeric probes. Also centromeric probes can be applied seperately in mFISH.
