What is annexin V binding?
Annexin V will bind to the PS-exposing apoptotic cell and can inhibit thereby the procoagulant and pro-inflammatory activities of the dying cell. These findings together with the presence of Annexin V in the extracellular space depict a novel (patho)Physiological significance for Annexin V in vivo.
How does annexin V staining work?
Annexin V, a 36-kDa calcium-binding protein, binds to PS; therefore, fluorescently labeled Annexin V can be used to detect PS that is exposed on the outside of apoptotic cells. Annexin V can also stain necrotic cells because these cells have ruptured membranes that permit Annexin V to access the entire plasma membrane.
Is annexin V specific to apoptosis?
Annexin V was shown to interact strongly and specifically with PS and can be used to detect apoptosis by targeting for the loss of plasma membrane asymmetry. Labeled annexin V can be applied both in flow cytometry and in light microscopy in both vital and fixed material by using appropriate protocols.
How is annexin V used to identify apoptotic cells?
Fluorescent conjugates of annexin V are commonly used to identify apoptotic cells. The human vascular anticoagulant annexin V is a 35–36 kDa, Ca 2 +-dependent phospholipid-binding protein that has a high affinity for the anionic phospholipid phosphatidylserine (PS).
What is annexin V staining?
Annexin V Staining. In normal viable cells, phosphatidylserine (PS) is located on the cytoplasmic surface of the cell membrane. However, in the intermediate stages of apoptosis, PS is translocated from the inner to the outer leaflet of the membrane, exposing PS to the external cellular environment where it can be detected.
What is the function of annexin V?
The human vascular anticoagulant annexin V is a 35–36 kDa, Ca 2 +-dependent phospholipid-binding protein that has a high affinity for the anionic phospholipid phosphatidylserine (PS). In normal healthy cells, PS is located on the cytoplasmic surface of the plasma membrane.
Where is annexin V found in the body?
The human vascular anticoagulant annexin V is a 35–36 kDa, Ca 2 +-dependent phospholipid-binding protein that has a high affinity for the anionic phospholipid phosphatidylserine (PS). In normal healthy cells, PS is located on the cytoplasmic surface of the cell membrane.
