Used in immunological research to quantify levels of interleukin-2 receptor (IL-2R) in biological samples from sheep. This kit enables researchers to study T-cell activation and immune responses in ovine models, which is particularly valuable in veterinary immunology and infectious disease research. It supports the investigation of diseases such as ovine pulmonary adenocarcinoma, parasitic infections, and other conditions involving immune system modulation. The assay is commonly applied in monitoring disease progression, evaluating vaccine efficacy, and assessing immunomodulatory treatments in sheep.
