Main antinuclear antibody patterns on immunofluorescence [1] Homogeneous immunofluorescence staining pattern of double stranded DNA antibodies on HEp-20-10 cells. Interphase cells show homogeneous nuclear staining while mitotic cells show staining of the condensed chromosome regions.
Immunofluorescence pattern of SS-A and SS-B antibodies. Produced using serum from a patient on HEp-20-10 cells with a FITC conjugate. Anti-SSA autoantibodies (anti–Sjögren's-syndrome-related antigen A autoantibodies, also called anti-Ro, or similar names including anti-SSA/Ro, anti-Ro/SSA, anti–SS-A/Ro, and anti-Ro/SS-A) are a type of anti-nuclear autoantibodies that are associated with ...
Anti-Scl-70 (also called anti-topoisomerase I after the type I topoisomerase target [1]) is an anti-topoisomerase antibody-type of anti-nuclear autoantibodies, seen mainly in diffuse systemic scleroderma (with a sensitivity of 28–70%), but is also seen in 10–18% of cases of the more limited form of systemic scleroderma called CREST syndrome.

An extractable nuclear antigen panel, or an ENA panel, tests for presence of autoantibodies in the blood that react with proteins in the cell nucleus.It is usually done as a follow-up to a positive antinuclear antibody test and when one is showing symptoms of an autoimmune disorder.
p-ANCA is associated with several medical conditions: [3] It is fairly specific, but not sensitive for ulcerative colitis, so is not useful as a sole diagnostic test. [4] When measured together with anti-saccharomyces cerevisiae antibodies (ASCA), p-ANCA has been estimated to have a specificity of 97% and a sensitivity of 48% in differentiating patients with ulcerative colitis from normal ...
Since this activity occurs in the nucleus of the cell ATA is a form of antinuclear antibody. Scleroderma results from the overproduction of collagen in affected tissues, one study claims that there is an increased density of Topoisomerase I sites in the collagen genes, and that the antibodies may be altering transcription at these loci. [7]
The remaining syllables of the INNs, as well as the column Source, are explained in Nomenclature of monoclonal antibodies. Types of monoclonal antibodies with other structures than naturally occurring antibodies. The abbreviations in the column Type are as follows: mab: whole monoclonal antibody; Fab: fragment, antigen-binding (one arm)
Immunofluorescence staining pattern of anti-Sp100 antibodies on HEp-20-10 cells. Two proteins, Sp100 and promyelocytic leukemia factor are localized to punctate domains in the nucleus (nuclear dots or nuclear bodies). These domains (few to 20) were found to form a donut-shaped structure when cells were starved of amino acids.
