Chromosomes: Methods for Preparation


Visualization of the genome is possible within a short time frame during a cell division, the metaphase stage. Chromosomes can be arrested, fixed and used for the analysis.

Keywords: chromosome; preparation; diagnostics; genetic disease; cancer

Human metaphase chromosomes (a) after fluorescence in situ hybridization (FISH) using the chromosome X‐specific centromeric probe labelled with spectrum orange and chromosome Y‐specific heterochromatin labelled with spectrum green; and (b) with the inverted DAPI (4′,6′‐diamino‐2‐phenylindole) banding (similar to G banding), allowing chromosomal identification.
