Recombinant Human TNFRSF4 protein, C-His-hFc Tag
Product Description
Cat
IMP-367
Official Symbol
TNFRSF4
Product Overview
Recombinant Human TNFRSF4 protein (NP_003318.1) (Met 1-Ala 216) was expressed in HEK293, fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.
Description
OX40 (CD134) and its binding partner, OX40L (CD252), are members of the tumor necrosis factor receptor/tumor necrosis factor superfamily, is known to break an existing state of tolerance in malignancies, leading to a reactivation of antitumor immunity. The interaction between OX40 and OX40L plays an important role in antigen-specific T-cell expansion and survival. OX40 and OX40L also regulate cytokine production from T cells, antigen-presenting cells, natural killer cells, and natural killer T cells, and modulate cytokine receptor signaling. In line with these important modulatory functions, OX40-OX40L interactions have been found to play a central role in the development of multiple inflammatory and autoimmune diseases, making them attractive candidates for intervention in the clinic. Conversely, stimulating OX40 has shown it to be a candidate for therapeutic immunization strategies for cancer and infectious disease.
Expression System
HEK293
Species
Human
Tag
C-His-hFc Tag
Predicted N Terminal
Leu 29
Form
Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Molecular Mass
The recombinant human TNFRSF4/Fc is a disulfide-linked homodimer after removal of the signal peptide. The reduced monomer consists of 436 amino acids and has a predicted molecular mass of 48.2 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh TNFRSF4/Fc monomer is approximately 68 kDa due to glycosylation.
Protein length
Met1-Ala216
Endotoxin
< 1.0 EU per μg of the protein as determined by the LAL method
Purity
> 85 % as determined by SDS-PAGE
Storage
Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it 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.
Reconstitution
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
