Osteoprotegerin (OPG), a TNF receptor superfamily, is expressed in many tissues including heart, kidney, liver, spleen, and bone marrow. Osteoprotegerin has osteoprotective effect and is critical in bone remodeling. Osteoprotegerin can bind to RANKL and inhibit the binding between TNFSF11 and RANKL, thereby neutralizing the RANKL function in osteoclastogenesis[1]. OPG is also involved in multiple biological processes of cancers. TNFRSF11B/OPG Protein, Human (CHO, Fc) is a recombinant human TNFRSF11B/OPG (E22-L201) with C-terminal hFc tag, which is produced in CHO cell[1][2].
