Used in biomedical research to quantify arginase 1 protein levels in mouse samples, particularly in studies related to immune regulation, macrophage activation, and inflammatory diseases. Helps researchers assess M2 macrophage polarization, as arginase 1 is a key marker for this cell type. Commonly applied in immunology, cancer research, and models of infection, allergy, and tissue repair. Enables high-throughput, specific, and sensitive detection of arginase 1 in serum, plasma, cell lysates, and tissue homogenates.
