If anyone's interested we made about 20 proteomics videos/lectures/tutorials mainly for grad students post-docs etc interested in proteomics

RT @WCMC_UCDavis: Don't forget to register for this upcoming hybrid seminar, join us Nov 6 at 10am-12pm either on Zoom or in-person at GBSF….

This was a little reels video we made for the @genomecenter Halloween symposium this year. Btw we do know what RNA is , but it was too fragile and got cut 😉 .

RT @wfondrie: Seems like a good time for a list some of my favorite truly #OpenSource #proteomics tools. In no particular order:. 1. Comet….

RT @DemichevLab: DIA-NN 1.9.2 is out! There are some major improvements, please check the release notes

These 2 I consider required reading. I have read them over 2-3 dozen times over the last decade or 2 . yes I'm old now. I didn't used to be. how did that happen? .

Happy to hear I'm wrong, but man I would not spend my energy on SILAC labeling these days compared to the alternatives. Even MS1 LFQ DDA with MBR on non silac samples seems better to me. that works a lot better now than it used to.

SILAC DIA shows promise but still I think you are far better off using that time and energy for more replicates than SILAC labeling.

I don't think the advantages of combining your samples far upstream is a real advantage any more like it used to be. I think you are far better off using sample prep automation to decrease variation and having more replicates.

I think MS1 quant is just not as good as DIA MS2 level quant for most of the S/N range. You have far less curves to work with & at low S/N peak picking is seems far worse. Personally, I think combining them is the way to go which you can't do with SILAC DDA.

1. Designing a proper experiment that is not underpowered seems really tricky.

As I go through a recent SILAC experiment I'm becoming convinced it's a relic that should probably be discarded.

Way to go Thermo , another fine example of packaging. You know people with degrees in packaging do exist, maybe you should think about hiring some of them ? .

Received this with my evotips today. I wish I had a cute very tiny wizard in the lab! I feel like I’d pat his head for good luck , but he would always be grumpy because something was always broken

I almost never analyze SILAC samples anymore. Is it becoming less popular? Anyway I was really impressed with using the latest version of Fragpipe -w/ skyline integration for dda and Spectronaut 19 for DIA.

@genomecenter @DixonLydixon @KodiakCakes if you want the full dataset let me know😉.

Workflow = S-trap -> timsTOF HT -> diaPASEF -> Spectronaut 19 . Easypeasy.

Worlds first Pancake Proteomics? Could be!! We analyzed the pancakes we will be serving at our next @genomecenter coffee. Here are the top proteins you will be eating. We identified about 6K total. Credit to @DixonLydixon & Michelle in the lab
