The nano splits paper is out! Single cell seq and single cell proteomics on the same single (one) normal sized human cell! proteomicsnews.blogspot.com/2024/12/the-...
THE (real) single cell proteomics technique scSeq people love - NanoSplits- is out!
Check out one of my favorite techniques of the last few years - the NanoSplits paper here!   The first preprint of this study is somewhere...

How can you transfer peptide IDs between runs and still control your false discovery rate? Till now, the short answer is, you couldn't. Now you can, with PIP-ECHO.

Improved detection of differentially abundant proteins through FDR-control of peptide-identity-propagation
Quantitative analysis of proteomics data frequently employs peptide-identity-propagation (PIP) — also known as match-between-runs (MBR) — to increase the number of peptides quantified in a given LC-MS...

DNA copy number variation is strongly buffered at the protein level.

The buffering is much stronger than at the RNA level.

I took biochem in 2001, and for nearly 20 years read amino acid sequences daily… and I never knew Dayhoff named them or even the logic behind things like Q until last Friday (h/t Mike Janech). Also, this is another big Dayhoff moment for me. She was incredible!

The unofficial FeMS starter pack (until they join us on Bluesky :) anyway. If you're a woman working with a mass spectrometer please ask to be added! All women are welcome!

Nice work. Please check out our recent work demonstrating uncontrolled FDR for match between runs in popular LFQ tools. www.biorxiv.org/content/10.1...

My perspective on CVs for DIA-based #proteomics is out in JPR

It explores how normalisation, the CV formula and software parameters affect the outputs. It suggests parameters to use for biological and technical studies and provides an R package to calculate CVs.

Calculating and Reporting Coefficients of Variation for DIA-Based Proteomics
The coefficient of variation (CV) is a measure that is frequently used to assess data dispersion for mass spectrometry-based proteomics. In the current era of burgeoning technical developments, there ...
