In this video, we demonstrate an assay utilizing fluorescence microscopy to detect the adhesion of cancer cells to neutrophil extracellular traps (NETs). In the test wells, there is a notable increase in the number of fluorescently labeled cancer cells adhering to NETs, whereas wells treated with DNase exhibit reduced cancer cell adhesion to NETs.

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.
FAQs
Marker choice depends on the species, sample, and experimental question. CD66b and Ly6G serve as surface markers, while myeloperoxidase provides a lineage-associated protein signal. Using these targets with microscopy, immunostaining, or flow cytometry can help identify neutrophils in different settings, while the selected marker should match the sample type and the information being sought.
Morphology identifies cells through their visible appearance, whereas marker-based approaches detect characteristic molecules. Microscopy can therefore support recognition based on cellular form, while immunostaining or flow cytometry provides molecular evidence through targets such as CD66b, Ly6G, or myeloperoxidase. Comparing these strategies helps researchers select an approach suited to the sample and desired measurement.
The distribution and abundance of detected neutrophils can indicate recruitment, activation, or accumulation in response to inflammation, infection, or tissue injury. These patterns provide a way to examine innate immune responses and host-pathogen interactions. In experimental studies, comparing detection results across conditions can show how inflammatory responses change over time or after treatment.
Begin by defining whether the goal is to identify cells, quantify them, or examine their location in blood, tissue, or another experimental sample. Morphology and microscopy support visual assessment, immunostaining supports tissue localization, flow cytometry supports immune profiling, and blood analysis supports evaluation of circulating cells. The research question and sample therefore guide method selection.
Microscopy provides visual information about cell morphology and distribution, whereas immunostaining links cellular location to targets such as CD66b, Ly6G, or myeloperoxidase. Flow cytometry enables marker-based immune profiling, while blood analysis focuses on circulating neutrophils. These approaches answer complementary questions, so combining methods can connect cell identity, location, and measured abundance.
Neutrophil detection helps investigators assess innate immune responses during infection, inflammation, and tissue injury. It also supports analysis of host-pathogen interactions and evaluation of therapies that alter inflammatory responses. In clinical or translational contexts, the resulting measurements can contribute to diagnosis and immune profiling by showing whether neutrophils are present, accumulating, or changing under a treatment condition.
