  • Title: Chromosomal R-banding with a monoclonal antidouble-stranded DNA antibody.
    Author: Magaud JP, Rimokh R, Brochier J, Lafage M, Germain D.
    Journal: Hum Genet; 1985; 69(3):238-42. PubMed ID: 2579892.
    Abstract:
    A monoclonal anti-DNA antibody (HB2) specific for poly dG- poly dC nucleotides was used to stain metaphasic lymphocyte or amniotic cell human chromosomes. HB2 fixation was revealed using either a peroxidase- or a rhodamine-labeled anti-mouse immunoglobulin antiserum. The staining pattern of the chromosomes was dependent on the HB2 concentration: R-banding could be observed at high antibody dilution. Previous trypsinization of metaphasic preparations demonstrated a precise and reproducible typical R-banding independent of the HB2 concentration. This technique appears to be an interesting alternative to other R-banding procedures. The specificity of the antibody allows a better understanding of the biochemical mechanism of R-banding.
