Human OX40 Full-length Gene in Lentivector, Endotoxin-free DNA

Description

OX40, also known as CD134, ACT35, TXGP1L and TNFRSF4, is a single-pass type I transmembrane glycoprotein of the TNF receptor superfamily (TNFRSF).  OX40 is regarded as a T cell co-stimulatory molecule that coordinates with other membrane­bound co-stimulators including CD28, CD40, CD30, CD27, and 4­1BB/CD137. OX40 is absent on naïve T cells and its expression is induced after engagement of the TCR by antigen presenting cells and co-stimulation by CD40/CD40 ligand and CD28/B7. OX40 was identified as the receptor for OX40 ligand/TNFSF4.  OX40/OX40L-mediated signaling is critical for establishing or reactivating long-term T-cell immunity and breaking immune tolerance in malignancies, leading to a reactivation of anti-tumor immunity. Engagement of OX40 on activated T cells with OX40 ligand on dendritic cells promotes T cell survival and proliferation, prolongs the immune response, and enhances the transition from effector to memory T cells. OX40 also regulates cytokine production from T cells, antigen-presenting cells, natural killer cells, and natural killer T cells. Mutations in the OX40 gene are associated with immunodeficiency 16 (IMD16). Blockade of OX40 signaling with antibody or soluble receptor is efficacious in animal models of allergic airway inflammation, graft­versus­host disease and autoimmune disease. Conversely, stimulating OX40 with an agonistic antibody has shown therapeutic potential for cancer and infectious disease.

NCBI Gene ID: 7293

 

Uniprot Entry: P43489

 

Construct Details: Full length human OX40/CD134 gene is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter, which can be used for both transient and stable expression in mammalian cells.  It can be co-transfected with the LentiPAK DNA mix (SKU# LP-001) into HEK293 cells to produce high titer lentiviral particles.

 

Vector Type: pLTC (lentiviral expression vector containing a heterologous CMV promoter, see the vector map above)

 

Formulation: Supplied with 10 μg of endotoxin-free plasmid DNA at 200 ng/μl in sterile TE buffer (pH8.0)

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CGGGAAGCAATAGCATGATA-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
