Transcription factors and chromatin co-condensate and generate forces that alter genomic structure and function

Researchers led by Yael David and Shixin Liu have published a Nature Communications study describing for the first time the mechanisms underlying the co-condensation between transcription factors and DNA. By performing dynamic single-molecule experiments using LUMICKS’ C-Trap® technology, they were able to prove the physiological importance of phase-separated sub-compartments (co-condensates)…

Dynamic single-molecule experiments expose catch bonds as key to cell strength and flexibility

In a recent Nature Materials publication, scientists show for the first time how certain types of molecular bonds known as “catch bonds” make it possible for cells to combine both mechanical strength to withstand forces and adaptability to change shape and move. By performing dynamic single-molecule experiments with LUMICKS’ C-Trap®,…

C-Trap^® experiments suggest tubulin lattice state dictates tau envelope formation

Tau is an intrinsically disordered microtubule-associated protein (MAP) that helps stabilize microtubules by forming an envelope around them. This stabilizing protein has been implicated in neurodegenerative diseases such as Alzheimer’s, where abnormal chemical changes promote detachment of tau from microtubules and the formation of long threads that eventually lead to…

m-Trap^® allows precise control of biological activities in synthetic membraneless organelles (MLOs) in real time

Until recently, the understanding of membraneless organelles (MLOs) was hindered by the inability to control their bioactivities in a precise manner. In a recent Nature Communications article from the lab of Huang and Sun, University of Hong Kong, researchers were able to overcome this obstacle by producing synthetic MLOs that…

Dynamic single-molecule analysis reveals non-linear stiffening of mitotic chromosomes

In a recent study performed by Vrije Universiteit Amsterdam and the University of Copenhagen, researchers used LUMICKS’ u-Flux™ laminar flow microfluidics system together with optical tweezers and fluorescence microscopy – features combined in LUMICKS’ C-Trap® – to shed light on the structural organization of mitotic chromosomes. When preparing to undergo…

C-Trap^® studies reveal GroEL-ES protein folding acceleration mechanism

In a recent Science Advances publication, the group of Sander J. Tans from the AMOLF Institute, The Netherlands, demonstrate for the first time, at the single molecule level, how the molecular chaperone GroEL-ES modulates protein chain collapse and stimulates protein folding. Using LUMICKS’ C-Trap®, they were able to follow and visualize…

Exploring biomolecular condensate dynamics with the C-Trap^® reveals viscoelastic fluid behavior

In a recent article published in Nature Communications by the group of Huan-Xiang Zhou from the University of Illinois, Dr. Archishman Ghosh and co-workers provided insights into the dynamics of biomolecular condensates. Using LUMICKS’ C-Trap® with a dual-trap optical tweezer configuration they obtained direct evidence showing that phase-separated biopolymer condensates…

C-Trap^® experiments reveal mechanism of protein-DNA co-condensate formation

In a recent publication in PNAS, researchers from the Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG) and the Deutsches Zentrum für Neurodegenerative Erkrankungen (DZNE) shed light on how proteins interact with individual DNA molecules to form co-condensates. Using LUMICKS’ C-Trap®, which combines optical tweezers, confocal microscopy, and…
