W18063F_ULEAF_CD137_4-1BB_Antibody_071621.png
Recombinant human TNFRSF9/4-1BB-Fc Chimera (Cat. No. 772606) (black circles) binds to immobilized recombinant human TNFSF9 (Cat. No. 750006). Ultra-LEAF™ purified anti-human CD137 (4-1BB) antibody (clone W18063F) (purple squares) inhibits the binding in a dose-dependent manner, whereas the GoInVivo™ purified rat IgG2a, κ isotype ctrl antibody (Cat. No. 400562) (gray triangles) does not have the effect. This antibody blocks the binding of 0.03 µg/mL recombinant human TNFRSF9/4-1BB-Fc Chimera to 0.5 µg/mL of immobilized recombinant human TNFSF9 with an ND50 = 0.01 - 0.06 µg/mL.

Description

TNFRSF9, also known as 4-1BB and CD137, is a member of the tumor necrosis factor receptor superfamily (TNFRSF). It is a costimulatory receptor similar to OX40, CD27, CD30, and CD40. The interaction of TNFRSF9 and its ligand, TNFSF9, leads to the activation of cytotoxic T cells, reactivation of anergic T lymphocytes, and induces T cell proliferation. TNFRSF9/TNFSF9 preferentially enhances the expansion of CD8+ T cells rather than CD4+ T cells, through the increase of IL-2Rα (CD25) and IL-2 expressions in CD8+ T cells. Among the TNFRSF members, TNFRSF9 is the most potent inducer of IL-2Rα expression on CD8+ T cells. In vivo studies with TNFSF9 knockout mice and with the agonistic anti-TNFRSF9 monoclonal antibody showed that TNFRSF9/TNFSF9 interaction keeps the optimal CD8+ T cell-mediated immune response against viral infections and tumors. The mouse TNFRSF9 has 60% identity to the human receptor at the amino acid level.

Related FAQs

Do you guarantee that your antibodies are totally pathogen free?

BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.

Does BioLegend test each Ultra-LEAF™ antibody by functional assay?

No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.

Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?

No, BioLegend does not test for pathogens in-house unless otherwise indicated.  However, we can recommend an outside vendor to perform this testing as needed.

Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?

We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
