Recombinant protein


RANKL and RANK are members of the TNF superfamily of ligands and receptors that play an important role in the regulation of specific immunity and bone turnover. RANK (receptor) was originally identified as a dendritic cell-membrane protein, which, by interacting with RANKL, augments the ability of dendritic. These dendritic cells then stimulate naïve T-cell proliferation, and promote the survival of RANK + T-cells. RANK is also expressed in a variety of tissues, including skeletal muscle, thymus, liver, colon, small intestine, and adrenal gland. The RANK/RANKL interaction is important in the regulation of osteoclastogenesis, and in dendritic cell-mediated T-cell immune responses. Impairments in RANK signaling have been implicated in the induction of expansile osteolysis and Paget's disease of bone (PDB2). Recombinant Human sRANK Receptor is a 19.3 kDa polypeptide containing the TNFR-homologous, cysteine-rich portion of the extracellular domain of RANK receptor (175 amino acid residues).

Biological Activity

Determined by its ability to inhibit sRANKL induced NF-kappaB in RAW264.7 cells in the absence of any cross-linking. The expected ED50 for this effect in the presence of 15 ng/ml of recombinant sRANKL, is 30–50 ng/ml.


Endotoxin level is <0.1 ng/μg of protein (<1EU/μg).


Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1–1.0 mg/ml. Do not vortex. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at-20°C to –80°C.
