摘要 |
The present invention relates to a method of detecting a target antibody, particularly a target autoantibody, in a sample, using a small molecule fluorophore-labelled target antigen, or a functional fragment, functional variant or functional derivative thereof that specifically binds to the target antibody. Detection is typically carried out using immunodiffusion or immunoelectrophoresis. The invention also relates to methods of diagnosing disease, particularly autoimmune disease, using small molecule fluorophore labelled target antigens and autoantigens. Small molecule fluorophore labelled target antigens, including autoantigens, are also disclosed, as are uses such. |
