Used to measure interleukin-2 (IL-2) levels in biological samples from monkeys, such as serum, plasma, or cell culture supernatants. This kit is essential in immunological research to study T-cell activation and immune response in non-human primate models. It supports vaccine development, infectious disease studies, and evaluation of immunotherapies where monitoring cytokine production is critical. The assay provides high sensitivity and specificity, enabling accurate quantification of IL-2 in preclinical research settings.
