Used to measure levels of interleukin-8 (KC) in biological samples such as serum, plasma, or cell culture supernatants from mice. This assay is widely applied in immunology and inflammation research to evaluate immune responses, study chemokine activity, and assess the effects of drugs or treatments on inflammatory pathways. It enables researchers to quantify KC protein with high sensitivity and specificity, supporting studies in infection, autoimmune diseases, cancer, and tissue injury models.
