一般說明
Osteoprotegerin (OPG) is a member of the TNFR (tumor necrosis factor receptor) superfamily that can act as a decoy receptor for RANKL (receptor activator of nuclear factor κ-B ligand). The gene is mapped to human chromosome 8q24. The primary structure of OPG protein consists of seven distinct domains, four of which corresponds to the extracellular cysteine-rich domains of TNFR proteins and constitutes the soluble OPG. OPG is expressed in a wide variety of tissues including adult heart, lung, kidney, liver, spleen, prostate, lymph node and bone marrow. It is secreted both as a monomeric and a dimeric protein. Recombinant human OPG is a soluble 20kDa protein containing 174 amino acid residues.
應用
Osteoprotegerin (OPG) human has been used as a supplement in human cell culture during cytokine production.
生化／生理作用
Binding of soluble osteoprotegerin (OPG) to sRANKL (soluble receptor activator of nuclear factor κ-B ligand) inhibits osteoclastogenesis by interrupting the signaling between stromal cells and osteoclastic progenitor cells, thereby leading to excess accumulation of bone and cartilage. Changes in the level of serum OPG are associated with atherosclerosis and cardiovascular disorders. It might also be associated with malignancy and plays a regulatory role in multiple myeloma, prostate, breast, bladder and gastric carcinoma.

外觀
Lyophilized from 10 mM Tris pH, 7.5 + 75 mM NaCl.
重構
Centrifuge the vial prior to opening. Reconstitute in 5 mM Tris, pH 7.5 to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
