      Description
      OverviewA convenient kit for the identification of changes in the plasma membrane that occur during apoptosis. In apoptotic cells, phosphoatidylserine (PS) is translocated from the inner to the outer leaflet of the plasma membrane, allowing for the detection of PS on the cell surface. In the presence of Ca 2+, Annexin V exhibits a high affinity for PS and binds cells with exposed PS. Annexin V, when conjugated to a fluorophore, can be used to monitor apoptopic cells using flow cytometry or immunofluorescence microscopy.

      Intended useThe Calbiochem® Annexin V-FITC Apoptosis Detection Kit II is a non-isotopic system that can be used to detect phosphatidylserine on the outer leaflet of the cell membrane of apoptotic cells using flow cytometry or fluorescence microscopy.
      BackgroundApoptosis is a fundamental mode of cell death that serves as an important regulatory function during normal development, in tissue homeostasis, and in some disease processes. In normal viable cells phosphatidylserine (PS) is located on the cytoplasmic surface of the cell membrane. Upon induction of apoptosis, rapid alterations in the organization of phospholipids in most cell types occurs leading to exposure of PS on the cell surface. Recognition of PS by phagocytes in vivo results in the removal of cells programmed to die, thus apoptosis is not commonly associated with the local inflammatory response that accompanies necrosis. In vitro detection of externalized PS can be achieved through interaction with the anticoagulant annexin V. In the presence of calcium, rapid high affinity binding of annexin V to PS occurs. PS translocation to the cell surface precedes nuclear breakdown, DNA fragmentation, and the appearance of most apoptosis-associated molecules making annexin V binding a marker of early-stage apoptosis.
      Principles of the assay

      Figure 1: Annexin/Phosphatidyl Serine in Early Stages Apoptosis


      The Calbiochem® Annexin V-FITC Apoptosis Detection Kit II utilizes annexin V conjugated to FITC to bind to phosphatidylserine on the outer surface of cells undergoing apoptosis. Fluorescence is then detected by flow cytometry or fluorescence microscopy. Since membrane permeabilization is also observed in necrosis, necrotic cells will also bind Annexin V-FITC. Propidium iodide is included to help distinguish between viable, early apoptotic, and necrotic or late apoptotic cells. Necrotic cells will bind Annexin V-FITC and stain with propidium iodide while propidium iodide will be excluded from viable (FITC negative) and early apoptotic (FITC positive) cells. In the absence of phagocytosis final stages of apoptosis involve necrotic-like disintegration of the total cell, thus cells in late apoptosis will be labeled with both FITC and propidium iodide.
      Materials providedThere are sufficient reagents to label 20 samples with annexin V-biotin.
