Used in veterinary research and diagnostics to detect and quantify interferon-gamma (IFN-γ) levels in pig samples, such as serum, plasma, or cell culture supernatants. It is essential for monitoring immune responses in swine, particularly in studies related to infectious diseases like porcine reproductive and respiratory syndrome (PRRS), tuberculosis, and swine influenza. The kit supports vaccine development and evaluation by measuring cell-mediated immunity. It is widely used in laboratories focused on animal health, immunology research, and disease control programs in pig farming industries.
