CTLA 4 Recombinant Protein

Measured by its binding ability in a functional ELISA. Immobilized Human CTLA4 Protein Fc Chimera at 5μg/mL (100μL/well) can bind rhB7-1/ CD80 Protein with a linear range of 0. 1 - 2μg/mL. Measured by its binding ability in a functional ELISA. Immobilized Human CTLA4 Protein Fc Chimera at 5μg/ml (100μl/well) can bind rh PD-L1 /B7-H1 /CD274 Protein with a linear range of 1 - 10 ug/mL.

Lyophilized Protein should be stored at -20°C or lower for long term storage. Upon reconstitution, working aliquots should be stored at -20°C or -70°C. Avoid repeated freeze-thaw cycles.
