After this, the cell pellet was subjected to hypotonic treatment, fixed with acetic acid-methanol (1:3), and the lysate was filtrated through a 2-μm polycarbonate nuclepore membrane. Isolated micronuclei were air-dried on a glass slide and subjected to fluorescence in situ hybridization (FISH) using a mouse centromeric gamma satellite probe. Approximately half of the micronuclei isolated from vehicle control mice showed centromere signal(s). In these preliminary studies, the proportion of centromere-positive micronuclei was increased by treatment with spindle poisons (colchicine and vinblastine sulfate), decreased only slightly by 1-β-D-arabinofuranosylcytosine, and was generally unaffected by mitomycin C.}, pages = {245--251}, title = {Isolation of micronuclei from mouse blood and fluorescence in situ hybridization with a mouse centromeric DNA probe}, volume = {307}, year = {1994} }
