Used in immunological research to quantify macrophage chemokine factors in biological samples such as serum, plasma, and cell culture supernatants. Enables researchers to study inflammation, immune response, and disease mechanisms including autoimmune disorders, infections, and cancer. Commonly applied in preclinical studies to assess macrophage activation and chemokine expression under various experimental conditions. Supports high-throughput screening and biomarker validation in clinical and translational research settings.
