sRANK Receptor, human recombinant
Plays an important role in the regulation of specific immunity and bone turnover
Product Overview
Product Name: sRANK Receptor, human recombinant
Alternate Name/Synonyms: soluble Receptor Activator of NFkB Ligand, TNFSF11, TRANCE (TNF-related activation-induced cytokine), OPGL, ODF (Osteoclast differentiation factor)
Gene Symbol: RANKL
Accession #: O14788
Gene ID: 8600
Source: E. Coli
Appearance: Lyophilized powder
Physical Form Description: Sterile filtered through a 0.2 micron filter. Lyophilized from 10 mM Sodium Phosphate, pH 7.2.
Molecular Weight: 19.3 kDa
Purity by SDS-PAGE: ≥98%
Purity by HPLC: N/A
Endotoxin Level: < 0.1 ng/μg of protein (<1EU/μg).
Biological Activity: Determined by its ability to inhibit sRANKL induced NFkappaB 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.
Reconstitution Instructions: Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. 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.
Storage Temp.: -20°C
Shipping: Gel pack
Background Information: 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 cells to stimulate naïve T-cell proliferation in a mixed lymphocyte reaction, to promote the survival of RANK + T cells, and to regulate T-cell-dependent immune response. RANKL, which is expressed in a variety of cells including osteoblasts, fibroblasts, activated T-cells and bone marrow stromal cells, is also capable of interacting with a decoy receptor called OPG. Binding of soluble OPG to sRANKL inhibits osteoclastogenesis by interrupting the signaling between stromal cells and osteoclastic progenitor cells, thereby leading to excess accumulation of bone and cartilage. Recombinant rat sRANKL is a 19.4 kDa polypeptide comprising the TNF homologous region of RANKL (174 amino acid residues).
