ABSTRACT:
The invention provides fragments of GAD.sub.65 that are specifically reactive with at least one class of GAD.sub.65 autoantibody. Most fragments are substantially free of N-terminal amino acids that would otherwise limit solubility. Different fragment contain epitopes for different classes of GAD.sub.65 autoantibodies. The fragments are used in methods of diagnosing and treating insulin dependent diabetes mellitus and stiff man syndrome.
