Description: The monoclonal antibody OX40 reacts with rat CD134, a 50-kDa glycoprotein belonging to the TNFR superfamily. CD134, which is also known as OX40, is expressed on activated T cells, TH1, TH2, TH17, and Tregs, but not on naive CD4 or CD8 T cells or most memory cells. CD134 is also inducible on NKT cells, neutrophils, and NK cells. CD134 binds to CD252 (OX40L) to mediate T cell expansion and survival, as well as memory T cell generation. Finally, CD134 is involved in Treg suppression and tolerance. Applications Reported: This OX40 antibody has been reported for use in flow cytometric analysis. Applications Tested: This OX40 antibody has been tested by flow cytometric analysis of stimulated rat splenocytes. This can be used at less than or equal to 0.125 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Excitation: 633-647 nm; Emission: 660 nm; Laser: Red Laser. Filtration: 0.2 µm post-manufacturing filtered.

The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor has been shown to activate NF-kappaB through its interaction with adaptor proteins TRAF2 and TRAF5. Knockout studies in mice suggested that this receptor promotes the expression of apoptosis inhibitors BCL2 and BCL2lL1/BCL2-XL, and thus suppresses apoptosis. The knockout studies also suggested the roles of this receptor in CD4+ T cell response, as well as in T cell-dependent B cell proliferation and differentiation.
