In situ hybridisation

Definition

noun

A type of hybridization that detects and localizes the presence of specific DNA sequence within tissue samples (‘’in situ’’) when a labeled DNA or RNA probe binds with it via complementary base pairing.


Supplement

DNA ISH can be used to determine the structure of chromosomes. Fluorescent DNA ISH (FISH) can, for example, be used in medical diagnostics to assess chromosomal integrity. RNA ISH (hybridization histochemistry) is used to measure and localize mRNAs and other transcripts within tissue sections or whole mounts.


‘’Abbreviation:’’ ISH

‘’Alternative form:’’ ‘’in situ’’ hybridization
