| Abstract (en) | Different superresolution microscopy techniques have often characteristic advantages but also limitations, which could be equalized with a suitable combination of these techniques. In this project the single molecule localization microscopy (SMLM) was successfully combined with structured illumination microscopy (SIM) to a get a deeper insight in the chromatin organisation of cells. This combined approach allows to put precisely localized (10 nm-range), optical isolated fluorophores (SMLM) in context with highly resolved (100 nm-range) spatial information (SIM). Using this correlative approach with a suitable mounting medium (VECHATSHIELD/Glycerol mixture) and fluorophores, evidence was found that nucleosomes in U20S-Scc1 cells are arranged mainly in nanocluster with four and seven nucleosomes. |
