Used in immunological research to quantify levels of interleukin-2 receptor (IL-2R) in biological samples from goats. This kit enables researchers to study T-cell activation and immune response in caprine species, particularly in the context of infectious diseases such as caseous lymphadenitis or paratuberculosis. It supports monitoring of immune system dynamics during vaccine development, disease progression studies, and evaluation of therapeutic interventions. The assay is suitable for serum, plasma, and cell culture supernatant samples, providing a tool for high-throughput analysis in veterinary research and diagnostic laboratories.
