Used in immunological research to measure levels of Interleukin-2 in biological samples from bovine sources. Helps assess T-cell activation and immune response in cattle, supporting studies in veterinary immunology, vaccine development, and disease progression such as bovine leukemia or respiratory infections. Enables quantitative analysis in cell culture supernatants, serum, and plasma, providing insights into cytokine dynamics during infection or treatment. Widely applied in agricultural research and pharmaceutical testing involving bovine models.
