Used in biomedical research to quantify neutrophil chemotactic protein 2 (NAP-2/CXCL7) levels in biological samples such as serum, plasma, and cell culture supernatants. Helps investigate inflammatory processes, immune responses, and diseases involving neutrophil activation, including arthritis, sepsis, and atherosclerosis. Enables researchers to assess the role of CXCL7 in chemokine signaling and evaluate potential therapeutic targets in inflammation and cancer.
