Principle of the Assay:
An ENA Ouchterlony assay employs the basic principles of immunodiffusion by incorporating a tissue extract which contains antigens important in many autoimmune diseases. The assay has great utility as: a screening assay, a specific antibody identification assay, and a relative titering assay. The results can be read within 12-24 hours. Scl-70, Ro/SS-A, and Jo-1 antibodies may require 36-48 hours for precipitation. (1)(2)]]> J of Immunol, Vol: 96, 1966, p 464.]]> Arthritis Rheum, Vol: 23, 1980, p 617.]]>
