Recombinant Human TNFRSF11B,His-tagged

Cat. No. : TNFRSF11B-143H
Product Overview : RecombinantHuman OCIF produced inE.colicells is a single, non-glycosylated, polypeptide chain containing amino acids 201-401 and having a molecular mass of 31 kDa which includes a 4 kDa His tag. The OPG is purified by proprietary chromatographic techniques.
Description : Osteoprotegerin, which is a member of the tumor necrosis factor receptor superfamily and is involved in the regulation of bone metabolism. OPGand its ligand (OPGL) are cytokines regulating osteoclasto-genesis. OPGL binds to receptors on the surface of preosteoclasts and stimulates their differentiation into active osteoclasts. This leads to osteoresorption. OPG inhibits this osteoclasto-genesis (OPG is secreted by osteoblasts, and binds to OPGL, thus inhibiting maturation of osteoclasts and osteoresorption). The degree and activity of osteoresorption depend mainly on the balance between OPG and its ligand (OPGL); factors increasing OPGL expression mostly reduce OPG expression and vice versa.
Source : Escherichia Coli.
Physical Appearance : Sterile Filtered White lyophilized (freeze-dried) powder.
Purity : Greater than 80.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Formulation : The protein was lyophilized from a concentrated (1 mg/ml) solution with 1X PBS, 0.1% SDS and 1 mM DTT.
Solubility : It is recommended to reconstitute the lyophilized Osteoprotegerin in sterile 18 MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Applications : 1. Positive control for Western blot; 2. Antibody production; 3. Protein assay
Stability : Lyophilized Osteoprotegerin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution OCIF should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
