N-term |
C-term |
|
Purity |
> 95% as determined by BisTris PAGE > 95% as determined by HPLC |
Endotoxin Level |
Less than 1EU per μg by the LAL method. |
Biological Activity |
Measured by its binding ability in a functional ELISA. Immobilized Human OX40, His Tag at 2μg/ml (100μl/well) on the plate can bind OX40 Ligand/TNFSF4 hFc Chimera, Human. Test result was comparable to standard batch. |
Expression System |
HEK293 |
Theoretical Molecular Weight |
40.95 kDa |
Apparent Molecular Weight |
Due to glycosylation, the protein migrates to 50-60 kDa based on Bis-Tris PAGE result. |
Formulation |
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). |
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
Storage & Stability |
Upon receiving, the product remains stable up to 6 months at -20 °C or below. Upon reconstitution, the product should be stable for 3 months at -80 °C. Avoid repeated freeze-thaw cycles. |
Target Background |
Tumor necrosis factor ligand superfamily member 4 (TNFSF4) is also known as glycoprotein Gp34, OX40 ligand (OX40L),which belongs to the tumor necrosis factor family. It is expressed on such cells as DC2s (a subtype of dendritic cells) enabling amplification of Th2 cell differentiation. |
