Used for the quantitative detection of human arginase in biological samples such as serum, plasma, and cell culture supernatants. This kit is widely applied in immunological research to study immune regulation, as arginase plays a key role in modulating T-cell function and nitric oxide production. It is also utilized in cancer research, particularly in studies involving myeloid-derived suppressor cells (MDSCs), which express high levels of arginase and contribute to tumor immune evasion. Additionally, the kit supports research in inflammatory diseases, asthma, and cardiovascular conditions where arginase activity impacts vascular tone and tissue remodeling. The assay enables high sensitivity and specificity, allowing researchers to measure subtle changes in arginase concentration across experimental conditions.
