Magnetic Transferrin Assay (MTA) as a novel approach for discovering serum exosome derived protein biomarkers in neurological diseases

We developed TF-based MNPs (TF-MNPs) to isolate blood-derived exosome in this study and isolated the blood-derived exosomes of patients with neuroinflammatory diseases, such as dementia, Parkinson’s disease and multiple sclerosis via this strategy and then evaluated the proteomic profiling of these exosomes to screen for a potential candidate biomarker. Blood was collected from 10 patients in each of the three disease groups. Over 800 serum exosome proteins were identified by highly sensitive nanoflow liquid chromatography-tandem mass spectrometry (LC−MS/MS).
