Definition of Fiber FISH
Fiber FISH: A cytogenetic (chromosome) laboratory technique in which FISH (fluorescence in situ hybridization) is done on chromosomes that have been mechanically stretched.
Fiber FISH provides a higher resolution of analysis than conventional FISH and yields more precise information as to the localization of a specific DNA probe on the chromosome.
The word "fiber" here refers not to dietary fiber but to a chromosome fiber.
