General Information

RANK ligand (RANKL), also called TRANCE, OPGL and ODF, is a member of the TNF family that is expressed in activated T cells, lymph nodes and in stromal cell lines. RANKL (TRANCE) interacts with its receptor RANK expressed on mature dendritic cells (DC) and mature osteoclasts, leading to the inhibition of apoptosis, probably through the upregulation of bcl-x. RANKL is, therefore, a useful tool for enhancing DC and osteoclast survival and activity. Osteoprotegerin (OPG, see Prod. No. ALX-522-007) is a potent inhibitor of RANKL.
