During this webinar, guest speaker Dr. Jan Spille discusses his work using advanced fluorescence imaging techniques to investigate transcription condensates. Hear how the Vutara VXL super-resolution microscope supports this research by enabling the imaging of various biological structures below the diffraction limit.
Transcription factors, coactivators, and RNA polymerase II form biomolecular condensates at super enhancer-controlled genes in mouse embryonic stem cells. The small size of these condensates makes them difficult to study with conventional techniques. However, we overcome this limitation with single-molecule imaging in live and fixed cells to reveal structural and dynamic properties of transcription condensates. Multi-color single molecule localization microscopy allows us to dissect the chromatin architecture at transcription condensates below the diffraction limit. Furthermore, tracking of single molecules inside condensates complements these studies in live cells.
