4012 – ANApro

The ANApro is a semi-quantitative immunoassay for the separate determination of IgG antibodies against nuclear and cytoplasmic antigens (dsDNA, RNP, Sm, SS-A, SS-B, Scl-70, CENP, Jo-1) in human serum. The ANApro is intended as an aid in the diagnosis of systemic autoimmune disorders in conjunction with other clinical and laboratory findings.

The appearance of autoantibodies directed against components of the cell nucleus is a characteristic feature of systemic autoimmune diseases, especially; systemic lupus erythematosus (SLE), Sjögren’s syndrome, progressive systemic sclerosis (PSS), mixed connective tissue disease (MCTD), rheumatoid arthritis (RA) and dermatomyositis. The detection of antibodies in patient samples is well established and plays an essential role in the diagnosis of systemic autoimmune diseases.

By allowing the detection of autoantibodies to dsDNA as well as autoantibodies to extractable nuclear and cytoplasmic protein antigens, ANApro offers a rapid and practical opportunity for the determination of the whole autoantibody pattern in systemic autoimmune diseases on one test plate. By combining specified recombinant antigens with selected highly purified antigens, maximum specificity for these parameters is guaranteed.

The ELISA (Enzyme Linked Immunosorbent Assay) is an immunoassay for the determination of specific antibodies. The strips of the microtiter plate are coated with test-specific antigens. If antibodies are present in the patient´s sample, they bind to the antigens. A secondary antibody conjugated with the enzyme peroxidase detects the generated immune complex. A colorless substrate is converted into the colored product. The signal intensity of the reaction product is proportional to the antibody activity in the sample. After stopping the signal intensity of the reaction product is measured photometrically.

The immunoassay is designed for manual professional in vitro diagnostic use.
