| 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). |
| Recombinant Human IL-13 Protein is expressed from Expi293 with His tag and Avi tag at the N-terminal. It contains Gly21-Asn132. |

| The protein has a predicted MW of 15.3 kDa. Due to glycosylation, the protein migrates to 15 kDa and 25-45 kDa based on the Tris-Bis PAGE result. |
|
| Immobilized Human IL-13, His Tag at 2ug/ml (100ul/well) on the plate. Dose response curve for Human IL-13Ra2, hFc Tag with the EC50 of 1.9ug/ml determined by ELISA (QC Test). The affinity constant of 0.7uM as determined in SPR assay (Biacore T200). See testing image for detail. |
