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 … Continue Reading

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® … Continue Reading
