C-banding

C-band·ing stain

a selective chromosome banding stain used in human cytogenetics, employing Giemsa stain after most of the DNA is denatured or extracted by treatment with alkali, acid, salt, or heat; only heterochromatic regions close to the centromeres and rich in satellite DNA stain, except for the Y chromosome its long arm usually stains throughout.

C-banding

a technique of chromosomal staining in which chromosomes are exposed to alkaline and then acid conditions, in order to reveal bands of constitutive HETEROCHROMATIN that are identified with Giemsa stain.
