Protocol for Plasma Extracellular Vesicle and Particle Isolation and Mass Spectrometry-Based Proteomic Identification.
Academic Article
Overview
abstract
Plasma extracellular vesicles and particles (EVPs) are enriched in biomolecules that reflect individuals' physiological and pathological states. Several studies have demonstrated the potential of human plasma EVPs as a novel liquid biopsy. Here we describe a protocol for human plasma EVPs isolation and proteomic characterization. We isolated human plasma EVPs by the classical ultracentrifugation method and performed mass spectrometry-based proteomic profiling. Using this protocol, researchers can reveal the plasma EVPs proteome and explore the clinical application of plasma EVPs proteins for developing disease biomarkers.
