TNFRSF11B/OPG Protein, Human (CHO, Fc)

Cat. No.: HY-P7053
COA Handling Instructions

Osteoprotegerin (OPG), a TNF receptor superfamily, is expressed in many tissues including heart, kidney, liver, spleen, and bone marrow. Osteoprotegerin has osteoprotective effect and is critical in bone remodeling. Osteoprotegerin can bind to RANKL and inhibit the binding between TNFSF11 and RANKL, thereby neutralizing the RANKL function in osteoclastogenesis. OPG is also involved in multiple biological processes of cancers. TNFRSF11B/OPG Protein, Human (CHO, Fc) is a recombinant human TNFRSF11B/OPG (E22-L201) with C-terminal hFc tag, which is produced in CHO cell.

Description

Osteoprotegerin (OPG), a TNF receptor superfamily, is expressed in many tissues including heart, kidney, liver, spleen, and bone marrow. Osteoprotegerin has osteoprotective effect and is critical in bone remodeling. Osteoprotegerin can bind to RANKL and inhibit the binding between TNFSF11 and RANKL, thereby neutralizing the RANKL function in osteoclastogenesis[1]. OPG is also involved in multiple biological processes of cancers. TNFRSF11B/OPG Protein, Human (CHO, Fc) is a recombinant human TNFRSF11B/OPG (E22-L201) with C-terminal hFc tag, which is produced in CHO cell[1][2].

Background

Osteoprotegerin (OPG), a glycoprotein, belongs to TNF receptor superfamily. OPG is expressed in many tissues besides osteoblasts, including heart, kidney, liver, spleen, and bone marrow. Human osteoprotegerin shares <85% aa sequence identity with mouse and rat. Mouse OX40 shares 94.5% aa sequence identity with rat[1].
Osteoprotegerin can bind to RANKL and inhibit the binding between TNFSF11 and RANKL, thereby neutralizing the RANKL function in osteoclastogenesis. Osteoprotegerin also protects large blood vessels from medial calcification. Increased osteoprotegerin levels have been consistently associated with the incidence and prevalence of coronary artery disease[1][3]. Osteoprotegerin is also involved in multiple processes of cancers, such as tumor survival, epithelial to mesenchymal transition (EMT), neo-angiogenesis, invasion, and metastasis[2].
Osteoprotegerin plays a critical role in bone remodeling, and has osteoprotective effect[1].

In Vitro

RANKL (human, 0-100 pg/mL, 36 h) promotes the proliferation of VSMC[5].

In Vivo

Osteoprotegerin (human, 5 mg/kg, i.v.) shows antiresorptive effects in rats[4].

Purity

Greater than 95% as determined by reducing SDS-PAGE.

Appearance

Lyophilized powder.

Formulation

Lyophilized after extensive dialysis against PBS, pH 7.4.

Endotoxin Level

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping

Room temperature in continental US; may vary elsewhere.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
