The MaxDiscovery™ Mouse IL-13 ELISA Test Kit is designed for quantitative determination of the concentration of mouse IL-13 in serum, plasma, and cell culture supernatant. Mouse interleukin-13 (IL-13) is a ~ 14 kDa protein composed of 131 amino acids. It is the latest identified cytokine to join the Th2 cytokine family. It was initially identified by screening mouse cDNA libraries for inducible genes. IL-13 exhibits pleiotropic effects on mouse GM CSF-derived bone morrow macrophages. IL-13 inhibits Ab-dependent cellular cytoxicity activity and production of nitric oxide and proinflammatory cytokines without affecting the phagocytic function of activated macroghages. Consistent with the ability of IL-13 to stimulate early hemopoietic precursors in vitro, IL-13 administration in vivo also induce extramedullary hemopoiesis and monocytosis in mice.
