Used in biomedical research to quantify levels of neutrophil chemokines in biological samples such as serum, plasma, and cell culture supernatants. Helps in studying inflammatory processes, immune responses, and disease mechanisms involving neutrophil recruitment, including infections, autoimmune disorders, and chronic inflammation. Commonly applied in preclinical studies to evaluate the efficacy of anti-inflammatory drugs and to monitor biomarker changes in experimental models. Provides a sensitive and specific means to measure chemokine concentration, supporting data interpretation in immunology and pharmacology research.
