Overview
Peptide diagnostics have evolved from early radioimmunoassays to sophisticated mass spectrometry-based proteomic panels.
Key Milestones
- 1959: Rosalyn Yalow develops radioimmunoassay (RIA)
- 1970s: ELISA replaces RIA for peptide detection
- 1980s: Monoclonal antibody-based peptide assays
- 1990s: Troponin peptides as cardiac biomarkers
- 2000s: Mass spectrometry-based peptide profiling
- 2010s: Point-of-care peptide diagnostics
Impact
Peptide biomarkers like troponin, BNP, and procalcitonin are now standard in clinical diagnostics. Yalow won the 1977 Nobel Prize for RIA development.
