PG - 24-8 AB - The development and application of a highly sensitive double-target fluorescence in situ hybridization (FISH) method in combination with immunohistochemistry for detection of chromosome 1 abnormalities in interphase nuclei of neuroblastoma samples is reported. An alpha-satellite probe specific for chromosome 1 and a VNTR probe that hybridizes to chromosome band 1p36.3 were hybridized to GD2 prestained neuroblastoma cells in double-target FISH experiments. The ratio of intact to deleted chromosome 1 homologs in the neuroblastoma cells was assessed. To demonstrate the reliability of the method described, four selected samples derived from different neuroblastoma stages are presented. FISH results correlated well with data obtained by conventional cytogenetic procedures. The technique described allows sensitive detection of chromosome 1 abnormalities in interphase nuclei and enables partial cytogenetic analysis of nondividing cells with a defined immunological phenotype.
