Used in immunological research to quantify IP-10 (CXCL10), a chemokine involved in inflammatory responses. The kit enables detection of IP-10 levels in biological samples such as serum, plasma, and cell culture supernatants. Commonly applied in studies of autoimmune diseases, viral infections (like HIV, hepatitis, and COVID-19), cancer immunology, and vaccine development. Helps assess immune activation and monitor disease progression or response to therapy. Widely used in clinical research and drug development for biomarker validation.
