Characterizing Extracellular Vesicles from Biological Fluids(생물학적 유체로부터 세포외 소포체 특성화)

Executive Industry Relevance

Characterizing extracellular vesicles (EVs) from minimal biological fluid volumes addresses a critical bottleneck in non-invasive biomarker discovery and disease monitoring. This workflow enables high-content EV phenotyping from scarce patient samples, supporting translational research and early-stage target validation. The approach enhances predictive confidence for biomarker-driven portfolio decisions in ocular and systemic disease pipelines.
