Used in immunological research to quantify chicken interleukin-8 levels in biological samples such as serum, plasma, or cell culture supernatants. Enables study of inflammatory responses in poultry, aiding in the development of veterinary diagnostics and evaluation of immune system activation during infections or vaccine trials. Supports research in avian diseases like avian influenza, salmonellosis, and colibacillosis by measuring IL-8 as a biomarker of inflammation. Commonly used in laboratories focused on poultry health, immunology, and infectious disease monitoring.
