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 … Continue Reading

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, … Continue Reading
