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…

Force-dependent actin filament-binding by α-catenin recorded with the C-Trap^®

A recent publication in the journal eLife describes a multidisciplinary study evaluating how the mechanical properties of actin filaments regulate the binding of associated proteins. Specifically, the researchers used the C-Trap® to demonstrate how applied forces on actin filaments enhance binding of cell–cell adhesion protein α-catenin, but not its homolog…

Researchers use the m-Trap^® and C-Trap^® to discover CRISPR-Cas9 properties that can help improve in vivo efficiency

A recent publication from the research lab of Dr. Bo Sun presents new findings in the field of gene editing that may help improve in vivo delivery of CRISPR-Cas9 complexes. The team investigated the DNA-binding properties of Staphylococcus aureus Cas9 (SaCas9), a smaller orthologue to the commonly used Streptococcus pyogenes…

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…

In vitro characterization of nucleosomes upon DNA unwrapping using the C-Trap^®

A recent publication in the journal Scientific Reports describes a new method to create arrays of nucleosome positioning motifs. Through sequential Gibson Assembly reactions, the researchers managed to clone a series of sequence motifs, with high affinity for histone octamers, into one DNA molecule. The approach is ideal to start…

Vesicle-like RNA–protein condensates characterized by the C-Trap^®

We were happy to find yet another publication from the lab of Dr. Priya Banerjee with results from C-Trap® analyses! This time his lab examined the formation and features of vesicle-like RNA–protein structures, which differ from the more known uniform droplets. Apart from offering new insights to an emerging field,…
