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 ICOS, hFc Tag at 1μg/ml (100μl/well) on the plate can bind B7-H2/ICOSLG, His, Cynomolgus. Test result was comparable to standard batch. |
Expression System |
HEK293 |
Theoretical Molecular Weight |
27.7 kDa |
Apparent Molecular Weight |
Due to glycosylation, the protein migrates to 50-70 kDa based on Bis-Tris PAGE result. |
Formulation |
Lyophilized from 0.22μm 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 |
B7-H2, also known as B7-related protein (B7RP1), ICOS Ligand, and CD275, is an approximately 60 kDa transmembrane glycoprotein in the B7 family of immune regulatory molecules. B7-H2 is a ligand for the T-cell-specific cell surface receptor ICOS. Acts as a costimulatory signal for T-cell proliferation and cytokine secretion; induces also B-cell proliferation and differentiation into plasma cells. |
