New preprint out!
In this study, we introduce NanoFLex, a strategy that combines #HaloTag variants with #nanobodies -based immunolabeling to enable rapid, OneStep-IF #lifetime #multiplexing. Possible due to SmartSecondaries fused to #HaloTag from @nanotag.bsky.social: www.biorxiv.org/content/10.6...

🧪🧬 New preprint!
What if the same biosensor could reveal how cysteine is regulated across life domains?

We introduce Cystector, a genetically encoded fluorescent biosensor for real-time cysteine monitoring in living cells.

Last project of the year: self blinking JF635 + lattice light sheet + #BigVolumeBrowser to deskew both volume and localization data (and render)

Let us know if your computer survived the cleaning process 😉. Mine will need this.

We also tried it recently and indeed, it blinks nicely without any smelly buffers or extra stuff added. Makes SMLM sample preparation a breeze. I hope soon new additional colors will be discovered, apart from the far red.

🎄 A glimpse into #NanoTag Christmas dinner - Glühwein outdoors, a shared dinner, and Schrottwichteln 🎁♻️ where funny, used items are exchanged and find a new home. The past year has been special for us as we celebrate 10 years. Grateful for our team, customers, and partners.
Here’s to what’s next 🥂

Self-blinking dye restores efficient use of nanobodies in single-molecule localization microscopy. Direct STORM relies on robust fluorophore blinking; observations suggest that AlexaFluor647 underperforms when coupled to nanobodies, thereby undermining the advantages of nanobodies. We show that the...

✨ Blinking #nanobodies that work for single-molecule localization 🔬
Our new preprint shows that the self-blinking dye JF635b restores robust, buffer-free blinking in #nanobodies, enabling reliable #dSTORM, #MINFLUX, and more, without chemical-switching buffers. Opening new possibilities for #ExM!

🧬 New paper out! We explored why #antibodies have kept their 2 binding sites. Turns out, this “divalence” is crucial for B-cell receptors to sense antigen clustering and trigger immune responses, especially for weak or low-density antigens.

- A postdoc to work on cancer extravasation (4-year project).
- A postdoc help in completing Filopodia-related lab projects (2-year).
- Multiple Marie Curie postdoc positions that will open in the fall.
- We will open a 5-year position to cover my teaching (70% research and 30% teaching).

🌞🦙 Summer makeover? You bet.
Our alpacas ditched the fleece to stay cool – maybe your antibodies should too.
sdAbs are high-performance tools made of just the antigen-binding domain (∼15 kDa, 3 nm). 🔬🧪Perfect for IF, super-resolution microscopy, IP & more.

Yes, it might be that in some synaptic type, other synaptotagmin isoforms are more dominant, but it is far from demonstrated that there is NO Syt1 in such synapses...
