Used in immunological research to quantify porcine interleukin-13 levels in biological samples such as serum, plasma, or cell culture supernatants. Enables study of immune responses in pigs, particularly in allergic inflammation, parasitic infections, and asthma models. Supports vaccine development and disease monitoring in veterinary research. Provides a sensitive and specific tool for detecting IL-13, a key cytokine involved in Th2-mediated immune regulation. Widely applied in preclinical studies and animal health diagnostics.
