We describe a protocol for isolation and purification of neutrophils from mouse bone marrow by density gradient centrifugation and for neutrophil labeling using CellTracker dyes. This represents a simple, fast, reproducible and economical method for obtaining large numbers of neutrophils for downstream functional studies or adoptive transfer and tracking experiments.

Neutrophils are among the first cells to arrive on the site of inflammatory immune response, and their functions and mechanisms have been studied extensively in vitro. We demonstrate a standard density gradient separation method to isolate human neutrophils from whole blood using commercially available separation media.

This video demonstrates the induction and visualization of neutrophil extracellular traps or NETs in pre-labeled neutrophils using patient serum containing anti-neutrophil cytoplasmic antibodies. Furthermore, using an impermeable DNA dye and fluorescence microscopy enables the visualization of NETs.

A method of quantitating neutrophil adhesion is reported. This method creates a dynamic flow environment similar to that encountered in a blood vessel. It allows the investigation of neutrophil adhesion to either purified adhesion molecules (ligand) or endothelial cell substrate (HUVEC) in a context similar to the in vivo environment with sheer stress.

Neutrophils play an important role not only in host defense against invading microorganisms, but are also involved in the immune surveillance of tumor cells. Here, we describe techniques related to the isolation of neutrophils with anti-tumor properties and methods for monitoring anti-tumor neutrophil function in vitro and in vivo.
FAQs
Chemotaxis directs neutrophils toward chemical signals released by injured or infected tissue. This guidance helps cells reach locations where microbes or tissue damage are present, linking local danger detection to a rapid cellular response. In biology, this movement is an early step that positions neutrophils for antimicrobial activity and participation in inflammatory coordination.
Phagocytosis allows neutrophils to engulf invading targets, after which reactive oxygen species and antimicrobial granules contribute to their destruction. These mechanisms provide complementary forms of antimicrobial activity rather than a single killing process. Their coordinated action helps neutrophils respond rapidly to microbes and supports effective innate defense against bacterial and fungal infections.
Extracellular traps are one of the mechanisms neutrophils use to destroy invading microbes. Alongside engulfment, reactive oxygen species, and antimicrobial granules, they expand the ways these cells can act against targets. Because neutrophil activity also shapes inflammation, extracellular-trap responses are relevant not only to microbial elimination but also to how surrounding tissue experiences the immune response.
Neutrophil responses protect the host by rapidly targeting microbes, yet the same coordinated activity contributes to inflammation at injured or infected sites. This dual role connects antimicrobial defense with the tissue environment in which the response occurs. Studying that balance helps explain how neutrophils can support host protection while also participating in inflammation and repair.
Investigating neutrophil function can clarify how failures or alterations in rapid innate defense relate to immune deficiencies and inflammatory disorders. Researchers can examine migration, engulfment, microbial destruction, and extracellular-trap activity as connected parts of the response. This biological context helps link cellular behavior with disease mechanisms and with efforts to understand abnormal inflammation.
Neutrophil function is relevant to therapies that aim to limit tissue damage without weakening antimicrobial defense. The central challenge is preserving the cells’ ability to respond to bacterial and fungal infections while controlling their contribution to harmful inflammation. For biology research, this makes neutrophils a useful focus for connecting host protection, inflammatory regulation, and tissue repair.
