ENAscreen

ENAscreen is an ELISA test system for the qualitative determination IgG antibodies against extractable nuclear antigens (ENA) in human serum or plasma. It is used in cases of suspected connective tissue disease (CTD).

Besides DNA and histones, autoantibodies may also target other nuclear antigens. These nuclear antigens were named extractable nuclear antigens (ENA), as originally they were extracted from the nuclei with saline solution. Autoantibodies to Smith antigen (Sm) which is also considered to be highly specific for SLE were the first anti-ENA detected. Thereafter, further subtypes of ENA i.e. ribonucleoproteins (RNP), the Sjoegren antigens SS-A and SS-B, Scl-70, and Jo-1 were identified. Each individual well of the ENAscreen test is coated with a mixture of six highly purified antigens. For further differentiation, a positive result with this ELISA may then be followed up with ENAcombi or the ORGENTEC test kits for quantitative determination of the individual ENA specificities.
