Recombinant Human TNFSF4 Protein (Gln51-Leu183), N-10×His-tagged
Product Description
Cat
IMP-9604
Official Symbol
TNFSF4
Product Overview
Recombinant human OX40 Ligand/TNFSF4 protein (Gln51-Leu183) with a 10-His tag at N-terminus was expressed in Mouse myeloma cell line.
Description
This gene encodes a cytokine of the tumor necrosis factor (TNF) ligand family. The encoded protein functions in T cell antigen-presenting cell (APC) interactions and mediates adhesion of activated T cells to endothelial cells. Polymorphisms in this gene have been associated with Sjogren's syndrome and systemic lupus erythematosus. Alternative splicing results in multiple transcript variants.

Bio-activity
Measured by its ability to induce IL-8 secretion in HT1080 human fibrosarcoma cells transfected with human OX40/TNFRSF4. Muller, N. et al. (2008) FEBS J. 275:2296. The ED50 for this effect is typically 1-5 ng/mL. Measured by its binding ability in a functional ELISA. When Recombinant Human OX40/TNFRSF4 Fc Chimera is immobilized at 10 ng/mL, the concentration of Recombinant Human OX40 Ligand/TNFSF4 that produces 50% optimal binding response is found to be approximately 0.5-3 ng/mL.
Endotoxin
<1.0 EU/μg of the protein by the LAL method.
Purity
>95%, by SDS-PAGE under reducing conditions and visualized by silver stain.
Storage
Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70 centigrade as supplied.
1 month, 2 to 8 centigrade under sterile conditions after opening.
