G-banding stain

G-band·ing stain

a chromosome-staining technique used in human cytogenetics to identify individual chromosomes, which produces characteristic bands; it utilizes acetic acid fixation, air drying, denaturing chromosomes mildly with proteolytic enzymes, salts, heat, detergents, or urea, and finally Giemsa stain; chromosome bands appear similar to those fluorochromed by Q-banding stain.

Synonym(s): Giemsa chromosome banding stain
