Used in immunological research to quantify CCL3 levels in biological samples such as serum, plasma, or cell culture supernatants. Enables study of inflammatory responses, immune cell recruitment, and disease mechanisms involving chemokine signaling. Commonly applied in research on infectious diseases, autoimmune disorders, and cancer immunology. Supports evaluation of therapeutic interventions by monitoring changes in CCL3 expression. Provides a sensitive and specific method for high-throughput analysis in preclinical and clinical studies.
