Source : Escherichia Coli. Recombinant Human OCIF produced in E.coli cells 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. 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.
Purity:
Greater than 80.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
Antibody Type:
Recombinant Antibody
Application Dilute:
It is recommended to reconstitute the lyophilized Osteoprotegerin in sterile 18MO-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
