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…

ZAP-S binding prevents the refolding of SARS-CoV-2 RNA, inhibits programmed ribosomal frameshifting

A new Nature Communications article sheds light into the mechanisms that govern programmed ribosomal frameshifting (PRF) in SARS-CoV-2 virus, as demonstrated by C-Trap experiments.

ParB sliding to non-specific DNA regions visualized using C-Trap^®

A recent work published in eLife by Francisco de Asis Balaguer et al. shed light on the interaction of ParB with DNA, the consequent DNA condensation, and the role of cytidine triphosphate (CTP) in this process – at a single-molecule level. Using the C-Trap® the researchers investigated the role of…

Using C-Trap^® to unravel different binding modes of architectural DNA-binding proteins at different ionic conditions and DNA conformation

A recent study by Szu‐Ning Lin et al. for the first time provided direct information on the dynamics of the interaction between HU and DNA and how this interaction is influenced by ionic conditions and DNA conformation.

New insights into the initiation of nucleotide excision repair found using C-Trap^®

A recent publication in PNAS shows how the catalytically inactive alkyltransferase-like protein (ATL) scans and recognizes detrimental DNA alkylation lesions. The C-Trap® with correlated optical tweezers and confocal microscopy enabled researchers to investigate how ATL interacts with DNA to identify alkyl lesions and interact with associated repair proteins. The findings…
