Recombinant Mouse TNFRSF4/OX40 Protein

Store the lyophilized protein at -20°C to -80 °C for long term.
After reconstitution, the protein solution is stable at -20 °C for 3 months, at 2-8 °C for up to 1 week.

OX40, also termed CD134 and TNFRSF4, is a T cell co-stimulatory molecule of the TNF receptor superfamilywhich plays a key role in the survival and homeostasis of effector and memory T cells. OX40 is expressed onCD4+ and CD8+ T cells upon engagement of the TCR by antigen presenting cells along with co-stimulation byCD40-CD40 Ligand and CD28-B7. The interaction between OX40 and OX40 ligand (OX40L) will occur whenactivated T cells bind to professional antigen-presenting cells (APCs). The T-cell functions, including cytokineproduction, expansion, and survival, are then enhanced by the OX40 costimulatory signals. OX40 signals arecritical for controlling the function and differentiation of Foxp3+ regulatory T cells. OX40-OX40L interactionregulates T-cell tolerance, peripheral T-cell homeostasis, and T-cell-mediated inflammatory diseases.
