Intended use:

The SeraSpot® ANA-12 IgG is an in vitro diagnostic device for the detection of antinuclear (ANA) and cytoplasmic antibodies of the IgG isotype directed against the following antigens: dsDNA, Nucleosomes, Sm, P0, Histones, U1 snRNP, Ro/SS-A 60 kDa, Ro/SS-A 52 kDa, La/SS-B, Scl-70, CENP-B and Jo-1 in human serum or plasma samples.

General information:

Connective tissue diseases are systemic inflammatory rheumatic diseases usually characterized by a chronic course (systemic connective tissue diseases) with overlapping symptoms (Overlap-Syndromes). Connective tissue diseases include:

  • Systemic lupus erythematosus (SLE) and subsets
  • Sjögren`s syndrome
  • Systemic sclerosis
  • Idiopathic (autoimmune) myositis
  • Mixed connective tissue disease (MCTD or Sharp syndrome)
  • Overlap syndromes

Connective tissue diseases are characterized by typical autoantibody profiles, all detectable with SeraSpot® ANA-12 IgG.

Principle of the test:

SeraSpot® ANA-12 IgG is a solid phase immunoassay based on the use of recombinant or purified native proteins / protein complexes and dsDNA as capture antigens printed in array arrangement (microspot array) on the bottom of the wells of 96-well microtiter plates. The antigens serve as capture molecules for autoantibodies to nuclear antigens (ANA). Bound antibodies are detected by Horseradish Peroxidase-(HRP)-labeled antibodies against human antibodies of IgG-type by substrate reaction with hydrogen peroxide and 3,3’,5,5’-Tetramethylbenzidine (TMB). At the site of formed immune complexes blue spots are developed by precipitated product from colorless substrate solution. Color intensity is correlated to the antibody concentration. Pale blue to dark blue spots are visible by eye.
