  • Title: A rapid method for identification of constitutive heterochromatin of secondary constriction regions of human chromosomes 1, 9, and 16.
    Author: Verma RS, Brat SV, Dosik H.
    Journal: J Hered; 1982; 73(1):74-6. PubMed ID: 7069192.
    Abstract:
    The secondary constriction regions (h) of chromosomes 1, 9, and 16 stained deep red by RBA (R-bands by BrdU using Giemsa)--a useful tool for demonstrating the constitutive heterochromatic heteromorphisms in these regions. The unusual staining pattern of bands p 12 to q11 of chromosome 3, which is late replicating, also is reported. The extended deep red region does not correspond to C-banding on chromosome 3. This technique does not require sequential banding by QFQ and CBG for detecting the h-region heteromorphisms.
