Characterization of a chromosomally complex lung cancer cell line using multiwell fluorescence in situ hybridization.

ABSTRACT

The chromosomal characterization of a non-small cell lung cancer cell line (NCIH358) is described. This characterization was achieved using a simple, cheap and technically straightforward multiwell fluorescence in situ hybridization (FISH) method. The many and complex chromosome rearrangements identified by this method could not be defined using conventional G-banded chromosome analysis, and have not been previously described. For the detailed characterization of complex cell lines, multiwell FISH has many advantages over more technically demanding and expensive FISH techniques, and opens up the possibility of screening for consistent rearrangements, leading to the identification of unique fusion genes.
