Recombinant Human IL13 protein, His-Avi-tagged, Biotinylated

Specification :
| Description : 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). | Source : HEK293 | Species : Human | Tag : His-Avi | Form : Supplied as 0.22um filtered solution in PBS (pH 7.4). | Molecular Mass : The protein has a predicted MW of 15.3 kDa.Due to glycosylation, the protein migrates to 15KDa and 35- 45 KDa based on Bis-Tris PAGE result | Protein length : It contains Gly21-Asn132. | Endotoxin : Less than 0.05EU per ug by the LAL method. | Purity : > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC | Storage : The product should be stored at -70°C. Please do not repeated freeze-thaw cycles. | Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
