Term Description

The ratio of chromosome 19q arm deletions to chromosome 19p arm deletions. Results are used to diagnose oligodendroglioma brain tumors and to determine best treatment options. Tumors with 19q/19p ratio <0.80 and ≥26% deleted cells are deemed deleted for 19q.

Part Description

LP62864-1   FISH
FISH (fluorescence in situ hybridization) is a cytogenetic technique used to detect and localize the presence or absence of specific DNA sequences on chromosomes. FISH uses fluorescent probes that bind to only those parts of the chromosome with which they show a high degree of sequence similarity. Fluorescence microscopy can be used to find out where the fluorescent probe bound to the chromosomes. FISH is often used for finding specific features in DNA for use in genetic counseling, medicine, and species identification. FISH can also be used to detect and localize specific mRNAs within tissue samples. In this context, it can help define the spatial-temporal patterns of gene expression within cells and tissues.
