Human Osteoprotegerin Recombinant Protein Lyophilized from Innovative Research has been recombinantly produced in E. coli. This is a Lyophilized protein buffered in with a purity of Greater than 98% by SDS-PAGE gel and HPLC analyses.

Endotoxin level is less than 0.1 ng per and#956;g (1EU/and#956;g)..

More Details:

• Species: Human
• Target: TNFRSF11B
• Purity: Greater than 98% by SDS-PAGE gel and HPLC analyses.
  
  Endotoxin level is less than 0.1 ng per and#956;g (1EU/and#956;g).
• Source: E. coli
• Storage Conditions: The lyophilized Osteoprotegerin recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted Osteoprotegerin is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing Osteoprotegerin recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.

Additional Information:
Osteoprotegerin (OPG) is a member of the TNFR superfamily that can act as a decoy receptor for RANKL. 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. OPG is expressed in a wide variety of tissues including adult heart, lung, kidney, liver, spleen, prostate, lymph node and bone marrow. OPG is secreted both as a monomeric and a dimeric protein. Its primary structure consists of seven distinct domains, four of which corresponds to the extracellular cysteine-rich domains of TNFR proteins and constitutes the soluble OPG. Recombinant human OPG is a soluble 20.0 kDa protein containing 174 amino acid residues.
