Used in biomedical research to quantitatively measure human Arginase 2 protein levels in biological samples such as serum, plasma, cell lysates, and tissue homogenates. This kit is particularly valuable in studies related to immune regulation, cancer, cardiovascular diseases, and metabolic disorders, where Arg2 activity plays a key role in modulating L-arginine metabolism. By enabling accurate detection of Arg2 concentrations, it supports investigation into disease mechanisms, therapeutic responses, and biomarker development. The assay is commonly applied in immunology, oncology, and neuroscience research settings.
