Human Beta 2 Glycoprotein 1 IgG ELISA kit

Apolipoprotein H (Apo-H), also known as (β2-glycoprotein I, beta-2 glycoprotein I), is a multifunctional apolipoprotein. β2-glycoprotein I has been implicated in a variety of physiologic pathways including lipoprotein metabolism, coagulation, and the production of antiphospholipid autoantibodies. In autoimmune disease, anti-apolipoprotein H (AAHA) antibodies, also called anti-β2 glycoprotein I antibodies, comprise a subset of anti-cardiolipin antibodies and lupus anticoagulant. These antibodies are involved in sclerosis and are strongly associated with thrombotic forms of lupus. The persistent presence of IgG and/or IgG beta 2 glycoprotein I (B2GPI) antibodies is a laboratory criterion for the diagnosis of antiphospholipid syndrome (APS).
