Used in immunological research to quantify pig macrophage colony stimulating factor (M-CSF) levels in biological samples such as serum, plasma, and cell culture supernatants. Enables monitoring of immune responses in swine, supporting studies on inflammation, infectious diseases, and vaccine development. Widely applied in veterinary research and agricultural science to assess macrophage activation and immune system regulation. Provides a reliable, sensitive, and specific measurement tool for evaluating M-CSF concentration in experimental models involving pigs.
