Human OX40, Fc 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 OX40 Ligand, His Tag (active trimer) (Cat. No. OXL-H52Q8) at 5 μg/mL (100 μL/well) can bind Human OX40, Fc Tag (Cat. No. OX0-H5255) with a linear range of 0.4-3 ng/mL (QC tested).

Quantitative Analysis of CTLA-4 x OX40 Bispecific Antibody in Human Serum by Intact Assay.
Immobilized Human OX40, Fc Tag (Cat. No. OX0-H5255) at 2 μg/mL, add increasing concentrations of CTLA-4 x OX40 Bispecific Antibody in 50% Human serum and then add Biotinylated Human CTLA-4, Fc,Avitag (Cat. No. CT4-H82F3) at 0.2 μg/mL. Detection was performed using HRP-conjugated streptavidin with sensitivity of 2 ng/mL (Intact assay, Routinely tested).
