The chromosome in situ suppression hybridization or chromosome painting technic was applied to confirm and eliminate the markers involving chromosome 21 segments using a chromosome 21 DNA library. The library ATCCLL21SNO2 was amplified, directly biotinylated using the polymerase chain reaction. The results demonstrated a translocation of chromosome 21 material on chromosome 2 and X and eliminate the origin of the marker. Thus, the technique provides an important tool to complement the conventional G-banding technic.
