Alternative Name Osteoprotegerin (TNFRSF11B Antibody Abstract)
  • Osteoprotegerin (OPG) or osteoclastogenesis inhibitory factor (OCIF) is a secretory glycoprotein belonging to TNF receptor superfamily. OPG consists of 401 amino acid residues, it has a molecular weight of 60 kDa as a monomer and 120 kDa as a disulfide-linked dimer and is produced in different tissues, e.g. bone, skin, liver, stomach, intestine and lung. Osteoprotegerin inhibits the recruitment, proliferation and activation of osteoclasts. Osteoclast formation activity may be monitored principally by determination of concentration ratio of osteoprotegerin ligand (OPGL)/OPG. Alteration of this ratio may be the cause of bone loss in many imbalances in bone metabolism such as osteoporosis, osteopetrosis, hypercalcemia, metastatic osteolytic lesions and rheumatic bone degradation.
  • Other Names: OPG, Osteoclastogenesis inhibitory factor, OCIF
  • Research Areas: Bone and cartilage metabolism
Research Area Cardiovascular, Atherosclerosis, Extracellular Matrix, Innate Immunity, Cytokines
Application Notes
  • Quality control: Indirect ELISA - to determine titer of the antibody SDS PAGE - to determine purity of the antibody
  • Otimal working dilution should be determined by the investigator.
Restrictions For Research Use only
Format Lyophilized
Reconstitution Add 0.1 mL of deionized water and let the lyophilized pellet dissolve completely. Slight turbidity may occur after reconstitution, which does not affect activity of the antibody. In this case clarify the solution by centrifugation
Buffer The antibody is lyophilized in 0.05 M phosphate buffer, 0.1 M NaCl, pH 7.2. AZIDE FREE.
Preservative Azide free
Storage 4 °C/-20 °C/-80 °C
Storage Comment The lyophilized antibody remains stable and fully active until the expiry date when stored at -20 °C. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles and store frozen at -80 °C. Reconstituted antibody can be stored at 4 °C for a limited period of time, it does not show decline in activity after one week at 4 °C.
