New mechanism of helicase-induced DNA unwinding from nicks found with the C-Trap^®

A study published in eLife shows how replication protein A (RPA) activates helicase Bloom syndrome protein (BLM) to unwind double-stranded DNA (dsDNA) bidirectionally from nicks. The C-Trap® enabled the researchers to simultaneously measure and visualize the DNA–protein interactions in real time. The findings highlight previously unknown mechanisms of BLM that…

Controlled ligand gradient through C-Trap^® facilitates DSM measurements

A publication in the journal Micromachines describes how researchers managed to control the concentrations of DNA-binding dyes in single-molecule optical tweezers experiments on DNA. They established a controlled concentration gradient with the multi-channel laminar microfluidics system integrated with their C-Trap® correlated optical tweezers and confocal microscopy. The study demonstrates a…

Single-molecule study assesses how cohesin complexes bridge DNA molecules using C-Trap^® correlated optical tweezers with fluorescence microscopy

In a new study published in the journal Science Advances, Gutierreu-Flux™Escribano et al. studied the role of cohesin complexes in DNA tethering to gain a better understanding of sister chromatid cohesion. Using the C-Trap correlated optical tweezers with fluorescence microscopy, they observed in real-time intermolecular (DNA–DNA) and intramolecular cohesin-derived DNA bridge…
