ProteomEdge data now on the Human Protein Atlas
Targeted MS-based proteomics using our DiscoveryEdge™175 panel was applied to a longitudinal pregnancy cohort across all three trimesters. The study demonstrated a median CV of 7.5% without any batch normalization — available on the Human Protein Atlas (November 2025).

How It Works

Three Steps to Absolute Quantification

01
Add plasma
Add an equivalent of 1 µL raw blood plasma directly to the pre-aliquoted, vacuum-dried panel plate well.
02
Digest together
Run your standard sample prep workflow. qRePS™ co-digest with your sample, establishing equilibrium with endogenous proteins.
03
Quantify by MS
Inject to your LC-MS/MS system. Use the supplied Skyline library for peptide identification and absolute quantification.
