特異性：This item specifically recognises human Annexin V (ANXA5), otherwise known as Lipocortin V, a calcium-dependent phospholipid-binding protein and member of the annexin family, which binds with high affinity and selectivity to phosphatidylserine (PS). The translocation of PS from the cytosolic leaflet to the outer leaflet of the plasma membrane, due to a loss in plasma membrane asymmetry during apoptosis, acts as an in vivo signal for the removal of the dying cell, by phagocytosis. Detection of PS using Annexin V therefore provides a reliable tool for the indication of early programmed cell death. Annexin V has also been identified as an anticoagulant protein in the blood coagulation cascade, by acting as an inhibitor of prothrombin activation. The presence of antibodies to Annexin V, are associated with systemic lupus erythematosus (SLE), recurrent spontaneous abortions and systemic sclerosis (SSc).
