OX40/TNFRSF4 Protein, Human (Biotinylated, HEK293, His-Avi)

Cat. No.: HY-P78189
COA Handling Instructions

OX40 (TNFRSF4), is a receptor for OX40 Ligand. OX40 is preferentially expressed by T cells. OX40 can be activated by OX40 Ligand, thereby functioning as a T cell co-stimulatory molecule. The OX40-OX40 Ligand interaction promotes effector T-cell survival and effectively induces memory T-cell generation, as well as enhances the helper function of Tfh for B cells, and also promotes the differentiation and maturation of DCs. OX40/TNFRSF4 Protein, Human (Biotinylated, HEK293, His-Avi) is a recombinant biotinylated human OX40 (L29-A216) with C-terminal Avi and His tag, which is produced in HEK293.

Description

OX40 (TNFRSF4), is a receptor for OX40 Ligand. OX40 is preferentially expressed by T cells. OX40 can be activated by OX40 Ligand, thereby functioning as a T cell co-stimulatory molecule. The OX40-OX40 Ligand interaction promotes effector T-cell survival and effectively induces memory T-cell generation, as well as enhances the helper function of Tfh for B cells, and also promotes the differentiation and maturation of DCs[1][2]. OX40/TNFRSF4 Protein, Human (Biotinylated, HEK293, His-Avi) is a recombinant biotinylated human OX40 (L29-A216) with C-terminal Avi and His tag, which is produced in HEK293.

Background

OX40 (TNFRSF4), a member of TNFR superfamily, is a receptor for OX40 Ligand. OX40 is preferentially expressed by T cells, but also found in natural killer T cells, natural killer cells, neutrophils, and human airway smooth muscle cells. Human OX40 shares <30% aa sequence identity with mouse and rat. Mouse OX40 shares 90% aa sequence identity with rat[1].
OX40 Ligand can activate OX40 and thereby functioning as a T cell co-stimulatory molecule. The OX40-OX40 Ligand interaction promotes effector T-cell survival and effectively induces memory T-cell generation, as well as enhances the helper function of Tfh for B cells, and also promotes the differentiation and maturation of DCs[1][2].
The interaction between OX40 Ligand with OX40 is essential for the generation of antigen-specific memory T cells, and induces host antitumor immunity[3]. But the over-upregulation of OX40 and OX40L may induce abnormal activation of Tfh cells and excessive production of autoantibodies, which leads to autoimmune disease[1].

In Vitro

OX40 increases expression of RANTES protein in HUVECs[4].

Biological Activity

Measured by its binding ability in SPR assay. Human OX40 Ligand Trimer His-Flag immobilized on CM5 Chip can bind Biotinylated Human OX40 His-Avi with an affinity constant of 1.00 μM.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Reconstitution Calculator

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
