Figure 2. The specificity of assay detecting anti-serpinB13 autoantibodies.
Serum binding activity to serpinB13 was measured in the sera of NOD mice that were considered as negative (A, [n = 13]), weakly positive (B, [n = 14]) or positive (C, [n-15]) for anti-serpinB13 autoantibodies. Each sample was divided and preincubated at 4°C overnight with BSA (left) or with serpinB13 (right) at 1.0 μg/mL.
