Recombinant Human IP-10/CXCL10

Description :
FAQ COA 已发表文献 (C-X-C motif) ligand (CXCL)10 (CXCL10), also known as IP-10,belongs to the ELR(-) CXC subfamily chemokine.CXCL10 was originally identified as an IFN-gamma -inducible gene in monocytes, fibroblasts and endothelial cells. It has since been shown that CXCL10 mRNA is also induced by LPS, IL-1 beta, TNF alpha, IL-12 and viruses. CXCL10 was originally identified as an IFN-gamma -inducible gene in monocytes, fibroblasts and endothelial cells.CXCL10/IP-10 exerts its function through binding to chemokine (C-X-C motif) receptor 3 (CXCR3), a seven trans-membrane receptor coupled to G proteins. CXCL10/IP-10 and its receptor, CXCR3, appear to contribute to the pathogenesis of many autoimmune diseases, organ specific (such as type 1 diabetes, autoimmune thyroiditis, Graves’ disease and ophthalmopathy), or systemic (such as rheumatoid arthritis, psoriatic arthritis, systemic lupus erythematosus, mixed cryoglobulinemia, Sjgren syndrome, or systemic sclerosis). In adition, CXCL10 has been reported to be a potent inhibitor of angiogenesis and to display a potent thymus-dependent antitumor effect.

Purity > 97% by SDS-PAGE and HPLC analyses. Biological Activity The biological activity determined by a chemotaxis bioassay using human peripheral blood T-lymphocytes is in a concentration range of 10-50 ng/mL. Fully biologically active when compared to standard. Endotoxin EUper 1g of the protein by the LAL method. Formulation Lyophilized from a 0.2 m filtered concentrated solution in 20 mM PB, pH 7.4, 50 mM NaCl. Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at -20C. Further dilutions should be made in appropriate buffered solutions.
