The research group of Prof. Christoph Cremer offers the following PhD project: Superresolution Microscopy of Genome Nanostructure


We have established a variety of superresolution light microscopy ("nanoscopy") methods for the "nanoimaging" of functional nuclear structures. Presently such methods include Structured Illumination Microscopy (SIM) with a laterally enhanced resolution of about 100 nm (twice enhancement of the conventional limit); Spatially Modulated Illumination (SMI) microscopy with an axially structured optical lattice, which has made it possible to measure the size of  cellular complexes with a spatial resolution down to a few tens of nanometer and to perform precise size measurements of the compaction status of small, specifically labelled chromatin domains, replication and transcription complexes; and Single Molecule Localization Microscopy techniques, in particular Spectral Position Determination Microscopy (SPDM) with conventional fluorophores. These methods have allowed us to image nuclear nanostructures also in 3D intact nuclei down to a lateral optical resolution in the macromolecular range in optical sections with a thickness of a few tens of nanometer. In the context of a variety of biological collaborations, present SPDM applications studied in the Cremer-Lab include the analysis of the spatial correlation of chromatin and epigenetic modification factors responsible for the structure and function of the cell nucleus (e.g. different types of histones, chromatin remodelling proteins; Polymerase II, and many more), as well as radiation induced repair protein complexes and radiation changes in chromatin nanostructure.
