Influence of cell fixation on chromatin topography

Original language description

Using in situ hybridization techniques, a fixation step must precede denaturation to prevent disintegration of the chromosomes. The analysis of nuclei fixed by paraformaldehyde, preserving the native structure (three-dimensional or 3D fixation and analysis) has become possible with the development of confocal microscopy; however, the analysis of those fixed by methanol and acetic acid, dehydrating the nuclei (two-dimensional or 2D fixation and analysis), remains a very valuable tool for practical use indiagnostics and also in many cases for research. We compared both types of fixation and analyses using different cell lines and different DNA probes. Fixation of cells by methanol and acetic acid leads to the enlargement of contact of nuclei with the slide surface, resulting in a substantial increase of nuclear diameter, flattening of the nucleus, and consequently to a distortion of gene topology.
