- In situ hybridization, fluorescent
An important molecular cytogenetic method for identifying chromosomes and parts of chromosomes, deciphering chromosome rearrangements, and locating genes on chromosomes. “Fluorescent” means emitting light that comes from a reaction within the emitter. “In situ” refers to the fact that this techniques is done with the chromosomes, cells or tissue in place (in situ) on a […]
- In situ hybridization
The use of a DNA or RNA probe to detect complementary genetic material in cells or tissue. In situ hybridization involves hybridizing a labeled nucleic acid to suitably prepared cells or tissues on microscope slides to allow visualization in situ (in the normal location).
