Used in immunological research to quantify levels of MIP-1β (CCL4) in biological samples such as serum, plasma, and cell culture supernatants. Helps in studying inflammatory responses, immune cell recruitment, and disease mechanisms including autoimmune disorders, infectious diseases, and cancer. Enables researchers to assess the role of MIP-1β in host defense and inflammation, supporting drug development and biomarker discovery. Suitable for high-throughput screening and clinical research settings where precise measurement of cytokine levels is required.
