Mc Cluskey, K.A. (author), Dekker, N.H. (author)TIRF (Total Internal Reflection Fluorescence) microscopy is a powerful tool for measuring the intra- and intermolecular dynamics of fluorescently-labeled single molecules. As TIRF measurements move to more complex biological systems with more fluorescent probes, the multi-band-pass dichroic that separates excitation from emission becomes...journal article 2023

Yang, Sora (author), Klughammer, N. (author), Barth, A. (author), Tanenbaum, M. (author), Dekker, C. (author)Single-molecule fluorescence imaging experiments generally require sub-nanomolar protein concentrations to isolate single protein molecules, which makes such experiments challenging in live cells due to high intracellular protein concentrations. Here, we show that single-molecule observations can be achieved in live cells through a drastic...journal article 2023

Kolbeck, Pauline J. (author), Tišma, M. (author), Analikwu, B.T. (author), Vanderlinden, Willem (author), Dekker, C. (author), Lipfert, Jan (author)DNA stores our genetic information and is ubiquitous in applications, where it interacts with binding partners ranging from small molecules to large macromolecular complexes. Binding is modulated by mechanical strains in the molecule and can change local DNA structure. Frequently, DNA occurs in closed topological forms where topology and...journal article 2023

(author)The eukaryotic replicative helicase CMG centrally orchestrates the replisome and leads the way at the front of replication forks. Understanding the motion of CMG on the DNA is therefore key to our understanding of DNA replication. In vivo, CMG is assembled and activated through a cell-cycle-regulated mechanism involving 36 polypeptides that...journal article 2023

Ramirez Montero, D.F. (author), Liu, Z. (author), Dekker, N.H. (author)DNA constructs for single-molecule experiments often require specific sequences and/or extrahelical/noncanonical structures to study DNA-processing mechanisms. The precise introduction of such structures requires extensive control of the sequence of the initial DNA substrate. A commonly used substrate in the synthesis of DNA constructs is...journal article 2023
