New plasma glycoproteomics method out of the @hecklab.bsky.social uses narrow-window DIA on Orbitrap Astral with Aurora Ultimate XT column. 50% more glycopeptide IDs vs. traditional approaches, with 181 glycoproteins detected across 7 orders of magnitude in just 10-40 minute runs. bit.ly/45bDXhv

🕷️ Spiders from our blood 🕷️ Check out our new paper from @hecklab.bsky.social describing how the spider-like immune regulator C4BP interacts with its native binding partners. 🔗 www.mcponline.org/article/S153... #MassSpec #StructuralBiology

We show that C4BP has two distinct binding modes, either involving a single “spider leg” or the entire spider-like structure wrapping around the target. Thanks to everyone involved! @victoryin.bsky.social, @hecklab.bsky.social, Jürgen, Johannes, Maryam, and Leendert

Fantastic day sharing knowledge with the brilliant researchers at NIH who valiantly work to advance the frontiers of science for the cause of improving human health. Thank you again for your service 🙏 🇺🇸

Excited to share our new preprint on “Complete Enzyme Clustering Enhances Coenzyme Q Biosynthesis via Substrate Channeling” A collaboration between @ShakhnovichLab and @MatteviLab Read on bioRxiv: www.biorxiv.org/content/10.1...

Science has more than doubled our life expectancy, revolutionized our quality of life, and powered unprecedented technological advancement. But can we afford to take scientific progress for granted? What happens when science funding is slashed, diversity is suppressed, and pseudoscience takes hold?

Spiders from our blood 🕷️ Excited to present our work with @hecklab.bsky.social at #ASMS2025 WP 611.

Check it out. Even if you are afraid of spiders, Tereza is very nice and knowledgeable

Always interested to go beyond trypsin and CID @tshamorkina.bsky.social, @tkadava.bsky.social and @lperezpaneda.bsky.social, @cinderbio.bsky.social & @sciex.bsky.social produced https:// www.biorxiv.org/content/10.1101/2025.05.26.656138v1 & @asms.org. A truly improved de novo sequencing approach

We explored the Excedion Pro Mass Analyzer with faster & more efficient EThcD capabilities, launched @asms.org, to more efficiently convert MS2 spectra to PSMs, as quality & unambiguous identification are more important parameters than peptide numbers. www.biorxiv.org/content/10.1...

We are excited to have it out: a combination of archaeal proteases and hybrid fragmentation for antibody de novo sequencing. Poster TP-005 #asms2025 #teammassspec It was a true team effort @lperezpaneda.bsky.social @tkadava.bsky.social @joostsnijder.bsky.social and @hecklab.bsky.social

Hi @carolynbertozzi.bskyverified.social . A 500 pieces puzzle that was made for Glycobiology GRC students using a #glycotime illustration from you ! Now ready for you to try it (tell me if someone from your lab is at glyco27 or SFG 2025 for delivery)

Super excited to share this as my first post with the 🦋 world! In my first co-correspondent article, we (@Mayra Borrero @Agnieszka Chacińska @IMOL Institute) look at the roles of lipids in mitochondrial protein import complexes (spoiler: there are plenty!) &call for methods (spoiler: there are few!)

Breakthrough Prize for Gerard 't Hooft, congratulations. Great day for Theoretical Physics and @utrechtuniversity.bsky.social. Hope this sort of fundamental science will remain supported in the near future. Congratulations.

Having Fun on Saturday in the @carolynbertozzi.bskyverified.social Lab with @davidsroberts.bsky.social. Have still to work out how the glycan can be attached to the P. But they do magic things here!

Epic review on all things cell surface-ome, great resource for the community 🙏
