What can HaloTag do for you?

Triggered fluorogenic labelling?
Molecular recording?
Photo-Chemically Induced Dimerisation?

Philipp Mauker's CHalo motif lets reagents do all three, and more.

Lipid imaging on the cover of @nature.com! Great times for lipid cell biology indeed. And a fantastic recognition of all the hard work by the team, especially Juan M. Iglesias-Artola and Kristin Böhlig (who made the cover). Link to article: www.nature.com/articles/s41...

The human UDP-Gal-4-epimerase is important for cellular biosynthesis of UDP-Gal and UDP-GalNAc. Both are important precursors for glycosylation. GALE KO abrogates cellular levels of these metabolites. GALE plays a role in cancer (pubmed.ncbi.nlm.nih.gov/31908526/) - so we decided to drug it!

Molecular Recording with HaloTag?
H2O2, GSH, Trx, LAP?

→ multiplexable reagents record diverse enzyme activities ratiometrically, without signal loss

Chemically Induced Dimerisation, modular & on-demand:

=> Fast, stepwise reagents for HaloTag-to-SNAP-tag heterodimerisation without a hook effect

Now preprinted: doi.org/10.1101/2025...

Congratulations to Philipp Mauker & the CHalo Crew for programming with HaloTag!

We boosted tumour-selective delivery of nano-formulated chemotherapeutics by transiently shaking up tumour blood vessels. The catch? You only get one shot at this ☝️ This #BMBF funded work, driven by a predominantly female team @lmumuenchen.bsky.social is available on the @biorxivpreprint.bsky.social
The delivery of nano-formulated drugs to solid tumours is selectively increased by co-application of the vascular disrupting agent CA4P https://www.biorxiv.org/content/10.1101/2025.08.10.669501v1

For ion-specific photocurrents across membranes: just let ionophores intermingle with photolipids.

A fully modular approach with easy access to large currents.

Stoked that this years-long sleuthing effort led by Peter Pohl is finally out! doi.org/10.1101/2025...

Congrats to our new Doctor Markus!
@m-markus.bsky.social pioneered chromocontrol by ideal efficacy photoswitching (doi.org/10.1101/2024...), TRPC5 photopharma (doi.org/10.1002/anie...), & switch-based photoacoustic imaging (doi.org/10.1002/anie... & doi.org/10.26434/che...) : a tour de force summa!

Misogeny and sexism is not always easy to recognise, but it's systematic and it paves the way for inequality, hate and violence. Took me painfully long to become angry enough about this. Feminism, and make it intersectional, is good for EVERYONE. #StopViolenceAgainstWomen #TagGegenGewaltAnFrauen

Thanks Stephan!

Feed is ordered like this:
(1) prioritises recent posts hashtagged #ChemBio or #ChemicalBiology (not case sensitive)
(2) then other recent posts with "chembio", "chemical biology" etc (not as hashes)
(3) then the "best 5%HN" of recent #ChemSky, #realtimechem, #FluorescenceFriday etc

A reminder for new folks. BlueSky does not have an algorithm to raise posts of interest. It is incumbent upon you to do so via reposting. Liking things only provides feedback to the poster but does not promote the post. The signal to noise ratio is taking a brief beating, so great to help curate.
