(A) FISH using whole chromosome paints for 1, 4 and 8 on human metaphase spreads. Chromosome painting probes were directly labeled with Texas Red (Chromosome 1) and FITC (Chromosome 4 and 8). (B) Detection of chromosomes 1, 4 and 8 in cytokinesis blocked MN in ex vivo γ-rays-irradiated peripheral blood lymphocytes of donor 2 (top panel) and donor 3 (bottom panel). (C) Detection of chromosome 1 in IR-induced micronuclei in donor 2 using whole chromosome painting probe (red colour) and centromere-specific probe (green colour). (D) Detection of chromosome 1 (red colour) and 4 (green colour) in IR-induced nucleoplasmic bridges (arrowheads). Chromosome 1 fragment is indicated by the arrow.
