Transcription factors and chromatin co-condensate and generate forces that alter genomic structure and function

Researchers led by Yael David and Shixin Liu have published a Nature Communications study describing for the first time the mechanisms underlying the co-condensation between transcription factors and DNA. By performing dynamic single-molecule experiments using LUMICKS’ C-Trap® technology, they were able to prove the physiological importance of phase-separated sub-compartments (co-condensates)…

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…

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…
