HoT auto-blinking probes enable real-time, super-resolution chromatin imaging in live cells and tissues.
HoT auto-blinking probes achieve real-time, super-resolution chromatin imaging in live cells and tissues with high stability and temporal resolution.
- Why it matters: Understanding chromatin architecture in living cells and tissues is crucial for insights into gene regulation and disease mechanisms, but suitable high-performance DNA probes are scarce.
- What they did: Researchers developed HoT probes—rhodamine-based, self-assembling, auto-blinking molecules conjugated to Hoechst—that permeate live cells and enable long-term, nanoscopic imaging of chromatin at high resolution.
- The result: The probes revealed nanoscale chromatin features, quantified DNA fiber dynamics, and visualized gene loci within chromatin footprints, advancing tools for studying chromatin structure in health and disease.
