Immunofluorescence staining pattern of anti-dsDNA antibodies on HEp-20-10 cells (left), Crithidia luciliae (centre) and rat liver (right). Anti-double stranded DNA (Anti-dsDNA) antibodies are a group of anti-nuclear antibodies (ANA) the target antigen of which is double stranded DNA.
The presence of anti-dsDNA antibodies is also linked with lupus nephritis and there is evidence they are the cause. Some anti-dsDNA antibodies are cross reactive with other antigens found on the glomerular basement membrane (GBM) of the kidney, such as heparan sulphate, collagen IV, fibronectin and laminin.
A value of greater than 1.5 units relative to a control serum is considered a positive ELISA test for the anti-histone antibodies. Patients with drug-induced lupus erythematosus typically have positive tests for anti-histone antibodies but do not have indications for anti-dsDNA antibodies. Patients with idiopathic systemic lupus erythematosus ...
Crithidia luciliae is a flagellate parasite that uses the housefly, Musca domestica, as a host. [1] [2] As part of the family of Trypanosomatidae, it is characterised by the presence of a kinetoplast, a complex network of interlocking circular double-stranded DNA (dsDNA) molecules.
This would result in the antibody-antigen complex not precipitating; leading to invalid results. [4] In addition, some anti-SS-B antibodies commonly identified in Sjögren syndrome may not be detected with this method. However, this method is economically feasible and specific to confirm a diagnosis.
Anti-mitochondrial antibodies (AMA) are autoantibodies, consisting of immunoglobulins formed against mitochondria, [1] primarily the mitochondria in cells of the liver.. The presence of AMA in the blood or serum of a person may be indicative of the presence of, or the potential to develop, the autoimmune disease primary biliary cholangitis (PBC; previously known as primary biliary cirrhosis).
36530115 TTT and 36381293 AAA (ratio % = 1.00409). 2087242 TCG and 2085226 CGA (ratio % = 1.00096), etc... In 2020, it is suggested that the physical properties of the dsDNA (double stranded DNA) and the tendency to maximum entropy of all the physical systems are the cause of Chargaff's second parity rule.

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.
