Characterization of Macrophage Extracellular Traps in Mouse Lung Tissue Samples

Executive Industry Relevance

Quantitative characterization of macrophage extracellular traps (METs) in murine lung tissue enables precise interrogation of innate immune mechanisms relevant to respiratory disease models. High-content immunostaining and confocal imaging of METs support mechanistic de-risking and target validation for immunomodulatory drug discovery. This workflow strengthens predictive confidence at the early discovery and preclinical interface for inflammation and infection portfolios.
