CERTIFICATE OF ANALYSIS AND DATA SHEET

PRODUCT DESCRIPTION:
Osteostat is the cytokine that binds to TNFRSF18/AITR/GITR and is important for interactions between activated T-lymphocytes and endothelial cells and may modulate T-lymphocyte survival in peripheral tissues. Osteostat is expressed at high levels in the small intestine, ovary, testis, kidney and endothelial cells after stimulation by lipopolysaccharides. Osteostat protein is detectable in human microvascular EC and is highly up-regulated by IFN-alpha and IFN-beta. Osteostat inhibit differentiation of osteoclasts from monocytic precursor cells. Osteostat suppresses the early stage of osteoclastogenesis via inhibition of macrophage colony-stimulating factorinduced receptor activator of NF-kappaB (RANK) expression in the osteoclast precursor cells. Osteostat does not inhibit lipopolysaccharide-induced RANK expression in monocytes and dendritic cells, or activation-induced RANK expression in T cells. Osteostat is a novel regulator of osteoclast generation and substantiate the major role played by the endothelium in bone physiology. The Human AITRL His-Tagged Recombinant Protein, produced in E. coli, is 15.7 kDa (calculated) protein containing 125 amino acid residues of the human AITRL and 14 additional amino acid residues - HisTag (underlined). The amino acid sequence of the recombinant human Osteostat is homologous to the extracellular domain of the human TNF18, Thr53-Ser177

FORMULATION:
Lyophilized from 0.5 mg/ml in 0.03 M Acetate buffer, pH 4

PURITY:
Greater than 95.0% as determined by: (a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE

STORAGE:
Although stable at room temperature for 3 weeks, it should be stored desiccated below -18°C. Upon reconstitution it should be stored at 4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles.

SOLUBILITY:
Add 0.2 ml of 0.1M Acetate buffer pH4 and let the lyophilized pellet dissolve completely. For conversion into higher pH value, we recommend intensive dilution by relevant buffer to a concentration of 10ug/ml. In higher concentrations the solubility of this antigen is limited
