Cation complexed DNA. A novel class of immunoadsorbents for anti-DNA antibodies
Abstract:
DNA can be precipitated as complexes with metal and organic cations. We have prepared these products using divalent metal cations (Cu2+, Mn2+, Ni2+, Zn2+, and Co2+) and ditetrazolium ions (blue tetrazolium and neotetrazolium). They are effective adsorbents, in vitro, for anti-nDNA antibodies and in reducing the titer of antinuclear antibodies in the sera from patients with autoimmune disease. They selectively adsorb most of the antinuclear components from a mixture of antimitochondrial and antinuclear antibodies.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Antibody Structure and Classes
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.
