TNFRSF11B (osteoprotegerin) functions as a soluble decoy receptor for RANKL, making it a critical regulator of osteoclast differentiation and a valuable tool for dissecting RANK/RANKL signaling. This recombinant construct covers the extracellular ligand-binding domain (aa 22–201) with a C-terminal Fc tag, and its biological activity is confirmed by an ED50 of less than 10 ng/mL in neutralizing sRANKL-mediated stimulation of U937 cells, corresponding to a specific activity exceeding 1.0 × 10⁵ IU/mg. These functional data support use in competitive inhibition assays, RANKL-blocking antibody screening, receptor-ligand interaction studies by SPR or BLI, and as a positive control in binding assays. Purity exceeding 95% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the criteria typical for cell-based neutralization experiments and drug discovery screens targeting osteoclastogenesis pathways.
