Lisandra, a fellow student studying for her PhD at the University of Buffalo, discussed a review paper titled "Proteomics biomaker discovery: It's more than mass spectrometry" with Eduardo Rivera Cintron and other students. The paper argues that discovering biomarkers requires more than just mass spectrometry and that biomarkers could enable earlier disease diagnosis and improved treatment. It also describes new proteomics technologies developed in recent decades like shotgun proteomics and plasma/tissue analysis that have aided biomarker discovery. However, the biomarker validation process is complex and typically only reaches the qualification step.
