Human IL-13 Protein (IL1-HE013) Summary

Product Description	Recombinant Human IL-13 Protein is expressed from E.coli without tag.It contains Gly21-Asn132.
Product Background	Interleukin-13 (IL-13) is a monomeric 17 kDa immunoregulatory cytokine that plays a key role in the pathogenesis of allergy, cancer, and tissue fibrosis. It is secreted by several helper T cell subsets, NK cells, mast cells, eosinophils, basophils, and visceral smooth muscle cells. Inhibits inflammatory cytokine production. Synergizes with IL2 in regulating interferon-gamma synthesis. May be critical in regulating inflammatory and immune responses. Positively regulates IL31RA expression in macrophages (By similarity).
Product Category	Recombinant Protein / Cell therapy / Cell culture / Cytokines
