Product Description | Recombinant Human TNFRSF11B Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Glu22-Leu401. |
Product Background |
Osteoprotegerin (OPG) is a key regulator in bone metabolism, that also has effect in vascular system. Studies suggest that osteoprotegerin is a critical arterial calcification inhibitor, and is released by endothelial cells as a protective mechanism for their survival in certain pathological conditions, such as diabetes mellitus, chronic kidney disease, and other metabolic disorders. |
