Abstract
Improved assays are provided for anti-acetylcholine receptor protein autoantibodies in the sera of patients with myasthenia gravis. The basis for the improved assays is the discovery that large quantities of acetylcholine receptor protein, that, for practical purposes in immunoassays, is immunologically indistinguishable from human muscle acetylcholine receptor protein, can be isolated from cells of the human medullablastoma-derived cell line TE671.
