Quantification and Visualization of Neutrophil Extracellular Traps (NETs) from Murine Bone Marrow-De

Neutrophils are one of the first cells to respond to an inflammatory stimulus, and are equipped with an assortment of antimicrobial and proteolytic enzymes to disarm and degrade bacterial pathogens. A novel mechanism of bacterial trapping, termed neutrophil extracellular traps (NETs), was recently described whereby neutrophils were shown to cast out web-like structures of chromatin, capturing and immobilizing invading pathogens. Herein we describe protocols to isolate murine bone marrow-derived neutrophils, and spectrophotometrically quantify, immunolabel, and visualize NET structures in vitro.
