Used in immunological research to quantitatively measure porcine interleukin-15 (IL-15) levels in biological samples such as serum, plasma, and cell culture supernatants. This kit is essential for studying immune responses in swine, particularly in inflammation, viral infections, and vaccine development. It supports research in veterinary medicine and animal health by enabling accurate assessment of IL-15, a cytokine involved in T-cell and natural killer (NK) cell activation and proliferation. Commonly applied in studies related to porcine reproductive and respiratory syndrome (PRRS), swine influenza, and other infectious diseases affecting the immune system.
