CTLA 4 Recombinant Protein

Measured by its binding ability in a functional ELISA. Immobilized Human CTLA4 Protein at 2μg/mL (100μL/well) can bind rhB7-1/ CD80 Protein Fc Chimera with a linear range of 2 - 50 ng/mL. Measured by its binding ability in a functional ELISA. Immobilized Human CTLA4 Protein at 10μg/mL (100μL/well) can bind rh PD-L1 /B7-H1 /CD274 Protein Fc Chimera with a linear range of 20 - 10000 ng/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.
