More than the sum of its parts: How harmonized proteomic data reveals meaning across disparate clinical cohorts

Why harmonization matters when proteomics data aren’t comparable

In high-throughput proteomics, data generated across different instruments, workflows, and cohorts can remain difficult to compare even after normalization.  Harmonization addresses these study specific differences, enabling datasets to align and reveal meaningful biological signals.  The the Global Neurodegeneration Proteomics Consortium (GNPC) illustrates this power by integrating 40,000 samples from 20 international groups to uncover insights not visible in isolated studies.  In this webinar, you’ll learn when normalization falls short and how harmonization strengthens cross-study and longitudinal analysis.

In this webinar you’ll:

  • Recognize when basic normalization falls short of making proteomic data truly comparable
  • Understand how harmonization aligns datasets across plates, batches, studies, and time
  • See how aligned datasets reveal biological signals that remain hidden after normalization alone
  • Determine when adding harmonization can strengthen cross-study and longitudinal analyses
