摘要:
The present invention relates to unglycosylated isolated and purified recombinant polypeptides comprising a fusion protein able to bind to autoantibodies produced in response to an autoimmune disease associated with an immune reaction to a TSH-receptor (TSHR). Also disclosed are methods of detecting and/or quantifying such autoantibodies using the isolated and purified recombinant polypeptides and respective kits.
