Analysis Note
The biological activity is measured by its ability to neutralize apoptosis of mouse L-929 cells treated with 50 ng/ml recombinant human TRAIL.
General description
Mouse OPG (amino acids 22-401) is fused downstream of the human IL-3Rα signal sequence to the C-terminal histidine-tagged Fc portion of human IgG1.
Physical form
Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline.
Biochem/physiol Actions
OPG is a soluble secreted member of the tumor necrosis factor receptor superfamily that lacks any apparent cell-association motifs. It regulates the formation of osteoclasts and is involved in the regulation of bone resorption and remodeling. Human and mouse OPG share approximately 84% and 94% amino acid sequence identity, respectively, with rat OPG.
