The IL-13R alpha 2 protein is a high-affinity receptor for interleukin 13 (IL-13) that acts as a decoy receptor and does not induce signaling upon IL-13 binding. Mice lacking this protein exhibit increased serum immunoglobulins, interferon gamma production, and bone marrow macrophage progenitor cell frequencies. IL-13R alpha 2 Protein, Mouse (HEK293, His) is the recombinant mouse-derived IL-13R alpha 2 protein, expressed by HEK293 , with C-His labeled tag.
