|Product name||Active Recombinant Human CTLA-4/CD152 Protein|
|Description||Active Recombinant Human CTLA-4/CD152 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Ala37-Phe162) of human CTLA-4 (Accession #NP_005205.2) fused with a 6×His tag at the C-terminus.|
|Bio-Activity||Measured by its binding ability in a functional ELISA. Immobilized lpilimumab at 1 μg/mL (100 μL/well) can bind Recombinant Human CTLA-4 with a linear range of 6-18 ng/mL.|
|Purity||> 90% by SDS-PAGE.|
|Endotoxin||< 1.0 EU/μg of the protein by LAL method.|
|Formulation||Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.|
|Storage||Store the lyophilized protein at -20°C to -80 °C for long term.|
After reconstitution, the protein solution is stable at -20 °C for 3 months, at 2-8 °C for up to 1 week.
|Reconstitution||Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water.|
