Product Overview
Tag | His |
Host Species | Human |
Accession | NP_003318.1 |
Synonym | OX40 Tumor necrosis factor receptor superfamily member 4; ACT35 antigen; OX40L receptor; TAX transcriptionally-activated glycoprotein 1 receptor; CD134; TNFRSF4; TXGP1L |
Background | OX40, also termed CD134 and TNFRSF4, is a T cell co-stimulatory molecule of the TNF receptor superfamily which plays a key role in the survival and homeostasis of effector and memory T cells. OX40 is expressed on CD4+ and CD8+ T cells upon engagement of the TCR by antigen presenting cells along with co-stimulation by CD40-CD40 Ligand and CD28-B7. The interaction between OX40 and OX40 ligand (OX40L) will occur when activated T cells bind to professional antigen-presenting cells (APCs). The T-cell functions, including cytokine production, expansion, and survival, are then enhanced by the OX40 costimulatory signals. OX40 signals are critical for controlling the function and differentiation of Foxp3+ regulatory T cells. OX40-OX40L interaction regulates T-cell tolerance, peripheral T-cell homeostasis, and T-cell-mediated inflammatory diseases. |
Description | A DNA sequence encoding the extracellular domain (Met 1-Ala 216) of human TNFRSF4 (NP_003318.1) was produced, fused with a His tag at the C-terminus. |
Source | HEK293 |
Predicted N Terminal | Leu 29 |
AA Sequence | Met 1-Ala 216 |
Molecular Weight | The recombinant human TNFRSF4 consists of 199 amino acids after removal of the signal peptide and has a predicted molecular mass of 21.7 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh TNFRSF4 is approximately 40-45 kDa due to glycosylation. |
Purity | Greater than 90% as determined by SDS-PAGE |
Endotoxin | < 1.0 EU per μg of the protein as determined by the LAL method |
Bioactivity | 1. Measured by its binding ability in a functional ELISA. 2. Immobilized human TNFRSF4-his at 2 ug/mL (100 ul/well) can bind- human TNFSF4/mFc, The EC50 of human TNFSF4/mFc is 29 ng/mL. |
Formulation | Lyophilized from sterile PBS, pH 7.4 |
Stability | Recombinnat Proteins are stable for up to 1 year from date of receipt at -70°C |
Usage | For Research Use Only |
Storage | Store recombinant protein under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. |
