First Claim
Patent Images
1. A method of clustering a subset of antigens of a plurality of antigens, said subset of antigens being reactive with a plurality of antibodies being derived from a plurality of patients having a disease, whereby the disease is associated with autoantibodies, the method comprising the steps of:
- (a) providing a plurality of test antigens, said test antigens being self-antigens or antigens from a library;
(b) assaying binding of said plurality of antibodies being derived from said plurality of patients with said plurality of antigens;
(c) assaying binding of a plurality of antibodies being derived from a plurality of individuals free of said disease with said plurality of antigens; and
(d) bioinformatically clustering a subset of antigens exhibiting an immune reactivity with said plurality of antibodies being derived from said plurality of patients having said disease, wherein said immune reactivity of (b) is classified as different from that exhibited with said plurality of antibodies being derived from said individuals free of said disease of (c).

12. A method of diagnosing a disease of a subject, the method comprising the steps of:
-
(a) providing a plurality of test antigens; (b) clustering a subset of antigens of said plurality of test antigens, said test antigens being self-antigens or auto-antigens from a library, said subset of antigens being reactive with a plurality of antibodies being derived from a plurality of patients suffering from said disease by; (i) assaying binding of said plurality of antibodies being derived from said plurality of patients with said plurality of test antigens; (ii) assaying binding of a plurality of antibodies being derived from a plurality of individuals free of said disease with said plurality of test antigens; and (iii) bioinformatically clustering said subset of antigens exhibiting an immune reactivity with said plurality of antibodies being derived from said plurality of patients having said disease of (i), wherein said immune reactivity is classified as different from that exhibited with said plurality of antibodies being derived from said individuals free of said disease of (ii); and (c) associating or deassociating the antibodies of said subject with a cluster resulting from step (b)(iii). - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
