Abstract
Disclosed are methods and kits useful in the differential diagnosis of multiple sclerosis. The method involves the use of an immunochemical reagent containing one or more prosomal antigens. Such a method typically involves: obtaining serum from a patient suspected of suffering from multiple sclerosis; contacting the immunochemical agent with the serum; and detecting the presence of immune complexes formed between the prosomal antigen and any antibodies reactive therewith present in the serum.
Claims6
A method useful in the differential diagnosis of multiple sclerosis comprising:
- a) contacting a sample containing antibodies of a subject with an immunochemical reagent comprising prosomal antigen;
- and
- b) detecting the presence of immune complexes formed between the prosomal antigen and any antibodies reactive therewith present in the sample.
A method to aid in the diagnosis of multiple sclerosis comprising the following steps:
- (a) binding prosomal antigen to the surface of the solid carrier;
- (b) contacting said bound prosomal antigen with a test sample from a subject;
- (c) allowing sufficient time for an immunological complex between the prosomal antigen and any autoantibodies that specifically bind to prosomal antigen present in the test sample to take place, thus forming a first solid phase and first liquid phase;
- (d) separating the first liquid and first solid phases;
- (e) contacting said first solid phase with an anti-human immunoglobulin labelled with metal sol that specifically binds to said autoantibodies in said immunological complex, thereby forming a second solid and second liquid phase;
- (f) separating the second solid and second liquid phases;
- (g) determining the presence of said autoantibodies by detecting the presence or the amount of said metal sol label on the second solid phase, wherein the presence of autoantibodies to prosomal antigens indicates multiple sclerosis in a subject.
