Congratulations

We did a plasma proteomics study on dengue disease severity in children with Tineke Cantaert and identified early markers of endothelial and inflammatory activation. Great work by @tshamorkina.bsky.social and Sofia! Thanks to all co-authors @hecklab.bsky.social.

These HTA proteases from archaea work great for mass spec-based antibody sequencing. Paper out now in final form at Cell Systems. Congrats to @tshamorkina.bsky.social @tkadava.bsky.social @lperezpaneda.bsky.social and @hecklab.bsky.social

Original (left) and corrected (right) Fig. 4a in the paper https://www.nature.com/articles/s41586-026-10305-0 showing the chemical structures of amino acids (only the right one) the left figure is just an embarrassment

I wonder... 🤔🤔🧪 #chemsky

a) what program did the authors use to make the original (left) figure in the paper? Wild guess, ChatGPT

b) how such high school science level of disgrace pass peer review in @nature.com?

Note this was Fig.4.a NOT in SI

Got an Orbitrap-based mass spec that couldn’t do STORI/direct mass technology before (any aside from the UHMR and Tribrid Ascend)?

This is a cool open-source implementation that even works on an Orbitrap Elite! #teammassspec

Is it not the more complicated form of mass spectroscopy?

Every day’s commute on bike. Not every day is the same

Since early 2024 we have been working with @brukercorporation.bsky.social on the first prototype timsOmni instrument, integrating an Omnitrap into a timsTOF. Here we report for the first time on the use of this instrument for protein-centric antibody sequencing. See www.biorxiv.org/content/10.1...

Congratulations to @tkadava.bsky.social, @hecklab.bsky.social and colleagues on this fascinating work!

It was such a pleasure to participate in such a diverse symposium with high quality contributions. And ended perfect with joint bike ride around Freising. Thank you @baybioms.bsky.social
