Eagle Biosciences Anti Beta 2 Glycoprotein 1 IgG ELISA Assay Kit is an indirect enzyme-linked immunosorbent assay (ELISA) kit designed for the quantitative measurement of IgG class antibodies directed against the β2-Glycoprotein 1 in human serum or plasma. Anti beta 2 Glycoprotein 1 IgG is intended for research use only and not intended for diagnostic procedure. Sample Types: serum, plasma. Range: 10 - 160AU/mL. Sensitivity: 0.47 AU/mL. Time: 2 hours ? The antiphospholipid syndrome (APS) is a disorder that presents peculiar symptoms: arterial and venous thrombosis, thrombocytopenia, ulcers of the lower limbs, hemolytic anemia, loss of the fetus during pregnancy and is associated with the presence of antiphospholipid antibodies. Antiphospholipid antibodies represent a large and heterogeneous immunoglobulins group, including anticardiolipin antibodies and lupus anticoagulant. The former are diagnosed by on their reactivity with cardiolipin or other anionic phospholipids in ELISA test, while the latter is detected in phospholipid-dependent coagulation tests (aPTT, KCT, dRVVT).
