P2 enrichment on the timsTOF HT achieves ~6000 protein groups from K2EDTA plasma while maintaining robust, reproducible performance across batches, days, operators, and laboratories.
- Why it matters: Enrichment improves plasma proteome depth but can be sensitive to preanalytical variation, risking loss of true biological signals needed for biomarker discovery.
- What they did: The study systematically tested eight blood collection types plus centrifugation, freeze-thaw, and pathogen inactivation using the P2 enrichment system, and assessed quantification with 16 heavy-labelled proteins in platelet-poor versus platelet-contaminated plasma.
- The result: In a cancer cohort, 97% of differentially abundant proteins kept the same direction of regulation after P2 enrichment versus neat preparation, supporting deep profiling that preserves biological information despite preanalytical variation.
