Enzyme immunoassay for the detection of autoantibodies IgG against ß2-Glycoprotein-1.
The anti-phospholipid syndrome (APS) is an autoimmune disorder which can comprise clinical conditions such as venous and arterial thrombosis, thrombocytopenia, myocardial infarction, recurrent spontaneous abortion and neurological complications.
Cardiolipin (CL) is a common, negatively charged, acid phospholipid. Autoantibodies associated with APS are directed not only against CL and similar phospholipides but also against phospholipid/protein complexes. ß2-glycoprotein 1 (ß2-GP-1; = apolipoprotein H) has been identified as a natural and essential co-antigen for CL-autoantibodies. The occurrence of CL/ß2-GP-1 autoantibodies is associated with a tendency towards thrombosis. Besides this diagnostic significance, these antibodies are believed to be directly involved in the pathogenesis of APS.
The EULISA ß2-Glycoprotein-1 IgG is intended for the quantitative or qualitative determination of IgG antibodies in human serum, directed against ß2-GP-1. The immobilised antigen is a highly purified preparation of human ß2-GP-1.
The test is fast (incubation time 30-30-30 minutes) and flexible (break apart wells, ready-to-use reagents). Six calibrators allow quantitative measurements; a negative and a positive control are used to check assay performance.
