De novo designed bright, hyperstable rhodamine binders for fluorescence microscopy by Bo Huang and team: www.biorxiv.org/content/10.1...
Fig. 4 Super-resolution microscopy in live and fixed cells with Rhobin. (A) Rhobin transiently binds rhodamine molecules and thereby constantly replenishes signal lost through photobleaching of dyes. (B-D) No-wash STED microscopy of live U2OS cells transiently expressing LifeAct-Rhobin2 labeled with 100 nM JFX650. (C, D) Zoom-ins of regions highlighted in (B) imaged either with confocal or STED microscopy. Scale bar: 20 μm (B) and 10 μm (C, D). (E-H) Rhobin enables timelapse STED microscopy of fast ER dynamics with minimal signal loss. U2OS stably expressing N-terminal tag fusions of SEC61B were stained with 1 μM Halo-JFX650 (HaloTag7, reHaloF) or 2 μM SiRhP (Rhobin2) and imaged at a frame rate of 0.387 fps for at least 100 time points. (F, G) Selected frames from timelapse acquisitions of Rhobin2:SEC61B labeled with SiRhP (F) or HaloTag7:SEC61B labeled with Halo-JFX650 (G). Scale bar: 2 μm.

Mean ± SD signal inside cells over time for indicated constructs. (I-K) PAINT-type super-resolution microscopy with Rhobin. Rhobin2-SEC61B was transiently expressed in U2OS cells and labeled with 5 nM SiRhP after chemical fixation. Imaging under no- wash conditions and near-TIRF illumination. (I) Repeated, but transient binding of SiRhP molecules to Rhobin2 at low nanomolar concentrations can be observed as intensity bursts in intensity time traces extracted from a diffraction-limited area. See movie S3 for raw data of binding-induced blinking. (J) Sum image across 10,000 frames of an image stack, simulating a diffraction-limited image. (K). Reconstructed image from localized molecules in the full stack.
