Distal bridging between nucleosomes by polycomb complex PRC2 identified with the C-Trap®

A recent study published in PNAS used single-molecule force spectroscopy to examine unknown interaction mechanisms between polycomb repressive complex 2 (PRC2) and chromatin. The authors evaluated arrays of multiple nucleosomes using their C-Trap® optical tweezers system and identified distal nucleosome bridging by PRC2. The findings provide a better understanding of…

New study highlights interconvertible RecA–ssDNA states with the help of u-Flux™ microfluidics

A recent publication in FEBS Letters describes how the presence of ADP and ATP affects the structural transitions that single-stranded DNA (ssDNA) undergoes upon RecA-filament assembly. The researchers used the u-Flux™ Laminar Flow Microfluidics combined with optical tweezers to demonstrate that the bacterial homologous recombination-enzyme exists in two interconvertible states.…

Researchers investigate the effects of biomolecular droplet structure on fusion times using the C-Trap®

In a recent publication, researchers at the University of Illinois at Chicago used the C-Trap® to study the relationship between structural properties of biomolecular condensates and their fusion times. They found that fusion times, an indicator of condensate density, varies depending on their structural organization. The findings highlight how physical…

Electrostatic effects on vimentin stiffness demonstrated with the C-Trap®

A recently published study from the lab of Prof. Sarah Köster at the University of Göttingen investigated how electrostatic conditions influence the mechanical properties of intermediate filament vimentin, such as structural stability. The researchers assessed these features by stretching the protein in different buffer conditions, using the C-Trap® with correlated optical…

Exploring mitochondrial translation processes with the C-Trap®

This month, we find the C-Trap®  featured in Nature Communications in an article published by the lab of Dr. Joanna Rorbach in which they describe mitochondrial translation initiation. The study provides insight into a relatively unexplored, yet exciting field that investigates the properties of mitochondrial ribosomes (mitoribosomes) during translation. Understanding…
