COALIZA Anticardiolipin
Automatically transferred from the PDF. Please compare details with the original document.
An enzyme linked immunosorbent assay (ELISA) for the quantitative determination of IgG and IgM anticardiolipin antibodies (aCL) in individuals with systemic lupus erythematosus (SLE) and lupus-like disorders (antiphospholipid antibody syndrome).
Test principle
Samples, controls and calibrators are incubated in micro wells, which have been coated with cardiolipin, allowing anticardiolipin antibodies (aCL) to bind. Unbound substances are removed by washing. An HRP conjugated detecting antibody, specific for human IgG or IgM is added and binds to the cardiolipin/aCL antibody complex. After a washing step, added enzyme substrate reacts with the conjugate. The intensity of the resulting colour is proportional to the content of IgG or IgM anticardiolipin antibodies in the sample.
