Figure 1. ELISA plate pre-coated by 2 µg/ml (100 µl/well) Human CTLA4, mFc-His tagged protein 11145 can bind Anti-CTLA4 Neutralizing antibody in a linear range of 0.13-16.0 ng/ml.

Figure 2. ELISA plate pre-coated by 2 µg/ml (100 µl/well) Human CTLA4, hFc tagged protein (11289) can bind Anti-CTLA4 Neutralizing antibody in a linear range of 0.64-80.0 ng/ml. In order to specifically detect 28031, mouse anti-human Fab-specific antibody was used as detection antibody.

Figure 3. HEK293 cell line transfected with irrelevant protein  (B) and human CTLA4  (A) were surface stained with anti-CTLA4 neutralizing antibody 1µg/ml (ipilimumab) followed by Alexa 488-conjugated anti-human IgG secondary antibody.
