Intended use

sRANKL, soluble receptor activator of nuclear factor (NF)-kB ligand (also: Osteoprotegerin ligand, OPGL) a member of the tumor necrosis factor (TNF) family, is the main stimulatory factor for the formation of mature osteoclasts and is essential for their survival. RANKL is produced by osteoblastic lineage cells and activated T lymphocytes. It activates its specific receptor RANK that is located on osteoclasts and dendritic cells. The effects are counteracted by OPG. Human sRANKL corresponds to free and OPG-bound RANKL. sRANKL is one of the key molecular regulation system for bone remodeling. An increase in RANKL expression leads to bone resorption and bone loss.
