Figure 1. GAD65Ab titer and inhibition of GAD65 enzymatic activity remains stable over time.

Figure 1

Longitudinal serum samples taken at the indicated time points were tested for their capacity to inhibit GAD65 enzymatic activity (white squares, right Y-axis) and their GAD65Ab titer (black squares, left Y-axix). GAD65 enzyme activity was measured in the absence and presence of serum samples. Inhibition of GAD65 enzyme activity is shown as percent inhibition. GAD65Ab titer was determined in a RBA and is reported as GAD65Ab index.
