Abstract
Introduction
Protein biomarkers are appealing to drug developers because they can be used early in the drug research pipeline, which allows early elimination of ineffective or toxic compounds. Although the promise of these biomarkers is clear, the path to successful implementation of protein biomarkers is not. Perhaps the discovery-based approach is not the best way to tap the potential of protein biomarkers.
