DEFINITION:
- C band or C banding
-
Differential staining of chromosomes to elicit chromosome bands, using a method that specifically stains the regions of the chromosomes that contain constitutive heterochromatin (C bands), particularly the pericentromeric areas, secondary constrictions of chromosomes 1, 9, and 16, and the distal segment of the long arm of the Y chromosome; the method consists of a denaturation and renaturation technique involving treatment of the chromosomes with acid, alkali, or heat before Giemsa staining. Called also centromeric banding.
