Mirror, mirror on the wall... 🪞 I'm super proud to have contributed to our latest work on left-handed DNA-PAINT! Here we introduce 6 new sequences using the left-handed enantiomers of our speed-optimized DNA-PAINT palette, enabling out-of-the-box 12-plex imaging without extra hybridization steps. 🌈🔬

Highly efficient 12-color multiplexing with speed-optimized DNA-PAINT. We are excited to share our latest paper in @natcomms.nature.com, using left-handed DNA to extend speed-optimized DNA-PAINT to 12 targets in a simple and straightforward way! 🧬👈🚀https://www.nature.com/articles/s41467-025-64228-x

Very excited to present our latest work: SPINNA, an analysis framework and software package for single-protein resolution data! 🖥️🤩 We can directly quantify stoichiometry and oligomerization from super-res (DNA-PAINT, RESI) images!! 🧬🎨

Spatial and stoichiometric in situ analysis of biomolecular oligomerization at single-protein resolution We are excited to present our latest work published in @natcomms.nature.com www.nature.com/articles/s41...

Excited to attend my first ever conference on single molecule approaches to biology by @GordonConf in beautiful Maine! Caught a fun 'Where's Waldo' moment in the hotel lobby - can you spot Ralf Jungmann and Luciano Masullo waving at me in the background? 🔍 @JungmannLab @l_masu

Happy Friday! To wrap up another exciting week of learning highly multiplexed DNA-PAINT in the @JungmannLab, here's a nice #cellfie of a rat hippocampal neuron stained for synaptic vesicle markers (Vamp2, VGlut1 and synaptotagmin), clathrin, neurofilament and peroxisomes.

My first preprint as a joint first author together with Otto Wirth and I couldn't be more excited! 📚 🔬 Exploring kinesin with MINFLUX during my Master's thesis was a blast while working with such talented minds in the Hell Lab. x.com/Stefan_W_Hell/… biorxiv.org/content/10.110…

Uncovering kinesin dynamics in neurites with MINFLUX

Neurons grow neurites of several tens of micrometers in length, necessitating active transport from the cell body by motor proteins. By tracking fluorophores as minimally invasive labels, MINFLUX is able to quantify the motion of those proteins with nanometer/millisecond resolution. Here we study the substeps of a truncated kinesin-1 mutant in primary rat hippocampal neurons, which have so far been mainly observed on microtubules polymerized on glass coverslips. A gentle fixation protocol largely maintains the structure and surface modifications of the microtubules in the cell. By analyzing the time between the substeps, we identify the ATP-binding state of kinesin-1 and observe the associated rotation of the kinesin-1 head in neurites. We also observed kinesin-1 switching microtubules mid-walk, highlighting the potential of MINFLUX to study the details of active cellular transport. ### Competing Interest Statement S.W.H. is inventor on patent applications WO 2013/072273 and WO 2015/097000 filed by the Max Planck Society that cover basic principles and arrangements of MINFLUX, including single-molecule tracking.
