W22033K_ULEAF_CD234_Antibody_022624
Recombinant human OX40/TNFRSF4-Fc chimera (Cat. No. 780804) (black circles) binds to immobilized recombinant human OX40L (Cat. No. 555706). Ultra-LEAF™ purified anti-human CD134 (OX40) (clone W22033K) (purple squares) inhibits the binding in a dose-dependent manner, whereas the Ultra-LEAF™ purified rat IgG2b, κ isotype control (Cat. No. 400644) (gray triangles) does not have the effect. This antibody blocks the binding of 0.05 µg/mL OX40/TNFRSF4 to immobilized 1 µg/mL recombinant human OX40L. ND50 range: 4 - 24 ng/mL.

Description

OX40 (ACT35, CD134, TNFRSF4) is an approximately 48 kD transmembrane protein belonging to the TNF receptor superfamily. It is a 249 amino acid glycoprotein with a 41 amino acid cytoplasmic tail, 20 amino acid transmembrane domain, and a 185 amino acid extracellular domain. OX40 is a costimulatory molecule implicated in long-term T cell immunity. It is a receptor for TNFSF4, OX40L, GP34, and also acts as a receptor for human herpesvirus 6B/HHV-6B. OX40 is primarily expressed on activated T cells, including CD4 and CD8 T cells, Th1, Th2, and Th17 cells, and regulatory T cells. The main source of OX40L is antigen presenting cells. OX40L can also be induced on activated B cells, mature dendritic cells, Langerhans cells, and macrophages. OX40 and OX40L interactions regulate the division and survival of T cells. It inhibits the conversion of effector T cells into regulatory T cells (Tregs) and promote the recall response in memory T cells. OX40 and OX40L interactions are also involved in the development of multiple diseases including allergic airway inflammation, graft-versus-host disease and autoimmune disease.

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.
