Anti-Osteoprotegerin antibody produced in goat

affinity isolated antibody, lyophilized powder

Synonym: Anti-OPG



General description

Osteoprotegerin (OPG) secreted by osteoblasts and osteogenis stromal stem cells belongs to the TNF receptor superfamily. OPG is expressed in bone marrow, osteoblasts, heart, lung, kidney, thymus, B lymphocytes, chondrocytes and smooth muscle cells. The ratio of OPG and receptor activator of NF-κB Ligand (RANKL) is crucial determining the bone mass. Receptor activator of NF-κB (RANK)/RANKL/OPG axis decides the bone biology. OPG binds RANKL and prevents the activation of osteoclasts, the cells that deplete bone mass. Excess levels of OPG lead to osteopetrosis while deficiency results in osteoporosis. The RANK/RANKL/OPG pathway mediates the activation of multiple pathways such as NF-κB, Akt, JNK, and MAPK
Anti-osteoprotegerin specifically reacts with recombinant mouse OPG. The antibody may cross react with human OPG (25% homology).


The antibody has the ability to neutralize the biological activity of recombinant mouse OPG.


purified recombinant mouse osteoprotegerin expressed in mouse NSO cells.


Anti-osteoprotegerin antibody may be used to neutralize mouse OPG at neutralization dose (ND50) of 0.5-2 μg/ml. The antibody is suitable for immunoblotting at a working concentration of 0.1-0.2 μg/ml.
