PG - Unit 8.8 LID - 10.1002/0471142905.hg0808s52 [doi] AB - Numerical and structural chromosome abnormalities can be accurately detected in cells from archived tissues using fluorescence in situ hybridization (FISH). This unit describes two common approaches to performing FISH in formalin-fixed, paraffin-embedded tissue. The first approach utilizes 4 to 6 microm tissue sections in cases for which preserving tissue morphology is necessary, and the second involves extraction of intact nuclei from 50 microm tissue sections. To interpret FISH results using 4 to 6 microm sections, an adequate number of nuclei must be evaluated to perform statistical analysis. Evaluation of 30 to 50 nuclei from the single cell suspension generally gives an interpretable result.
