Human CTLA-4, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.

Immobilized Human B7-1, Fc Tag (Cat. No. B71-H5259) at 2 μg/mL (100 μL/well) can bind Human CTLA-4, His Tag (Cat. No. CT4-H52H9) with a linear range of 0.1-2 ng/mL (QC tested).

Immobilized Human CTLA-4, His Tag (Cat. No.CT4-H52H9) at 2 μg/mL, add increasing concentrations of CTLA-4 x OX40 Bispecific Antibody in 50% Human serum and then add Biotinylated Human OX40, Avitag,His Tag (Cat. No. TN4-H82E4) at 1 μg/mL. Detection was performed using HRP-conjugated streptavidin with sensitivity of 4 ng/mL (Intact assay, Routinely tested).
