Executive Industry Relevance

Isolation of siderophore-containing extracellular vesicles (EVs) from Mycobacterium tuberculosis under iron-limiting conditions enables mechanistic interrogation of bacterial iron acquisition and vesicle-mediated communication. This workflow supports predictive confidence in early-stage target validation and informs translational research on host-pathogen interactions. The protocol's reproducibility and quantitative outputs position it as a reusable capability for biopharma discovery pipelines.
