COA Handling Instructions

4-1BB (CD137; TNFRSF9), a receptor of TNFSF9/4-1BBL, belongs to the tumor necrosis factor (TNF) receptor superfamily. 4-1BB is helpful for T cell activation and development, and also induces peripheral mononuclear cell proliferation and migration to the tumor microenvironment. 4-1BB is also involved in enhancing Nrf2 and NF-κB pathway mediated apoptosis of endothelial cells. Human 4-1BB protein is a surface glycoprotein with a transmembrane domain (187-213 a.a.). 4-1BB/TNFRSF9 Protein, Human (CHO, Fc) is the extracellular part (L24-Q186) of 4-1BB protein, produced by HEK293 cells with C-terminal hFc-tag.

Description

4-1BB (CD137; TNFRSF9), a receptor of TNFSF9/4-1BBL, belongs to the tumor necrosis factor (TNF) receptor superfamily[1]. 4-1BB is helpful for T cell activation and development, and also induces peripheral mononuclear cell proliferation and migration to the tumor microenvironment[2]. 4-1BB is also involved in enhancing Nrf2 and NF-κB pathway mediated apoptosis of endothelial cells[3]. Human 4-1BB protein is a surface glycoprotein with a transmembrane domain (187-213 a.a.). 4-1BB/TNFRSF9 Protein, Human (CHO, Fc) is the extracellular part (L24-Q186) of 4-1BB protein, produced by HEK293 cells with C-terminal hFc-tag.

Background

4-1BB, is encoded by TNFRSF9 (CD137, ILA), belongs to tumor necrosis factor (TNF) receptor superfamily. 4-1BB is a surface glycoprotein, expressed in a variety of cells, for example, T cells, B cells, natural killer (NK) cells, dendritic (DCs), eosinophils, and mast cells; even a variety of tumor cells such as human leukemia cells. It is widely spread in vascular smooth muscles, tumor vessel walls, and liver tissue of hepatocellular carcinoma. 4-1BB has a preference on CD8+ cells rather than CD4+ cells. It provides co-stimulatory signals and activates cytotoxic effects of CD8+ T cells and helps to form memory T cells. Finally, it promotes the immune system fighting against tumors. Moreover, CD137 binds CD137L to signal monocytes, increase their survival, proliferation and stimulate their migration and extravasation. In addition, it induces the release of various proinflammatory factors, leads to the influx of inflammatory monocytes into tissues and form an inflammatory environment[1]. Specifically, CD137 promotes the migration of monocytes/macrophages to tumor microenvironment by upregulating the expression of Fra1. It also promoted the differentiation of monocytes/macrophages into osteoclasts at the same time, thus providing a favorable microenvironment for the colonization and growth of breast cancer cells in bone. It provides a promising therapeutic strategy for metastasis of breast cancer[2]. Furthermore, CD137 signaling promotes endothelial cells (ECs) apoptosis through prooxidative and proinflammatory mechanisms, mediated by Nrf2 and NF-κB pathways, respectively[3]. The homology of 4-1BB protein in human and mouse was low, and the sequence similarity was 56.75%.

In Vitro

4-1BB (human; 1 μg/mL; 16 h) leads to induction of monocyte activation and induces Myc protein production[4].
4-1BB (human; 1 μg/mL; 10 d) prolongs survival of peripheral monocytes and (1 μg/mL; 1 h) induces expression of M-CSF[5].
4-1BB (human; 1.2-40 μg/mL; 7 d) exhibits nhancement of cell numbers dose-dependently[6].

Biological Activity

Binding ability is measured by immobilized ELISA, 1 µg/mL (100 µL/well) of immoblized recombinant human 4-1BB-Fc Chimera produces 50% optimal binding response approximately 5-15 ng/mL.

Purity

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

Appearance

Lyophilized powder.

Formulation

Lyophilized after extensive dialysis against PBS.

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.

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
