Aside from the whisper network, how are #teammassspec finding out how much certain instrument models are down for (service delays, backordered parts, things breaking all the time, etc)?

#AminoAcidAdvent Day 6: Cysteine (Cys; C)

Like Mork & Mindy, these stinky residues love to bond! Jerks like us break these bonds, with chemoproteomics trying to map, probe, and manipulate them. Leftovers stuck to S-S is a fun field but I love them for their antioxidant and metal binding abilities.

Amazing to see red blood cells moving through the gills! Don’t forget to check out the supplemental movies ;-)

one of the coolest things about ChatGPT is how you can actually just never use it. you can fill your whole entire life with simply not once using it. it's incredible.

So which AI peer review tool can tell me authors gave all the Code to make their Figures? 🧪

✅ Code uses right functions for plot type in Figure?

✅ Is there a 1:1 correspondence between Code and Figures?

❌ Automated reanalysis --> IMO this requires expert knowledge to know the data wasn't hacked

Proteomics + an elegant mechanism! I cannot wait to read in full! #proteomics #TeamMassSpec 🧪
Great to see Brenda Schulman’s team post their new bioRxiv paper. MS-based proteomics helped uncover a beautifully simple mechanism: cysteine levels tune metabolism by flipping the inverse stability of LRRC58 and its substrate CDO1.

No one is immune to aging but what exactly happens to our immune system as it ages? @thibaultcolombani.bsky.social takes a molecular dive into the immune system and talks about understanding age-induced immune altercations through single-cell proteomics.

Thanks!

Not yet, but I wouldn't expect huge benefits over the default LF models unless you are trying some exotic chromatography, collision energies or additives.

A bit dense, but the important message is dead simple:

We got to cite the E = mc² paper!

Kidding :)

The important part is that combinations of isotopes unlock 100-1000x gains in protein measurement speed.

🧪 I tried it and I'm happily surprised!

As long as it doesn't boil the oceans, I would run it on all new papers I read for:

🌎 Mapping the interrelatedness of claims -- papers are so complex now!

🔬 Calling out potential gaps -- so that I can know the experiments were properly controlled.

And, we are back with another presentation from this year's Research Fest. PTI's Senior Computational Scientist, Kevin McDonnell, talks about developing joint modeling (aka JMod) of mass spectra for empowering multiplexed DIA proteomics.
