Receptor activator of nuclear factor kappa-B ligand (RANKL or RANK Ligand) , also referred to as TNFSF11, TRANCE, OPGL and CD254, is a member of the tumour necrosis factor (TNF) family of cytokines that binds to its receptor RANK to control osteoclast differentiation, activation and survival (1-3). RANK and RANKL are key regulators of bone remodeling and regulate T cell/dendritic cell communications, and lymph node formation. RANK-RANKL signaling not only activates a variety of downstream signaling pathways required for osteoclast development, but crosstalk with other signaling pathways also fine-tunes bone homeostasis both in normal physiology and disease. In addition, RANKL and RANK have essential roles in lymph node formation, establishment of the thymic microenvironment, and development of a lactating mammary gland during pregnancy.

BP000050-GD13: Recombinant Human RANKL Protein

Source: E. coli-derived.
The activity of the RANKL protein (RANK ligand, TNFSF11, TRANCE, OPGL, CD254) is calculated by its ability to induce osteoclast differentiation on RAW 264.7 mouse macrophages. The ED50 for this effect is 2-12 ng/ml.
Endotoxin Level: <1.0 EU per ug of the RANKL protein by the LAL method.
Purity > 95%, by SDS-PAGE and SEC-HPLC.
Formulation: In PBS with 0.1% BSA.
