Annexins are a family of calcium-dependent phospholipid-binding proteins,
which bind to phophatidylserine (PS). Externalization of phosphatidylserine
residues in the outer plasma membrane of apoptotic cells allows detection via
Annexin V. Once the apoptotic cells are bound with labelled Annexin V, they
can be visualized with fluorescent microscopy or cytometry.
Since loss of membrane integrity is a pathognomonic feature of necrotic cell death, necrotic cells will stain with specific membrane-impermeant nucleic acid dyes such as propidium iodide. The membrane integrity of apoptotic cells can be demonstrated by the exclusion of these dyes.
