Annexin V Apoptosis Kit [FITC] Summary

• Description: Annexin V Apoptosis Kit [FITC] can identify apoptosis at an earlier stage than kits based on DNA fragmentation in the nucleus. However, it is like most assays and has limitations. Since Annexin V staining precedes the loss of membrane integrity which accompanies the later stages of cell death resulting from either apoptotic or necrotic processes, staining with Annexin V-FITC is typically used in conjunction with a live/dead dye such as propidium iodide (PI) or 7-Amino-Actinomycin (7-AAD) to allow the investigator to identify early apoptotic cells (PI negative, Annexin V-FITC positive) from dead cells (PI positive, AnnexinV-FITC positive). Viable cells with intact membranes exclude PI, whereas the membranes of dead and damaged cells are permeable to PI. For this reason, Annexin V staining has to be performed on live cells as opposed to assays which require para- formaldehyde/ethanol fixed cells.
  
  The Annexin V assay works in the following manner: Cells that are viable are both Annexin V-FITC and PI negative. While cells that are in early apoptosis are Annexin V-FITC positive and PI negative and cells that are in late apoptosis or already dead are both FITC Annexin V and PI positive. This assay does not distinguish between cells that have undergone apoptotic death versus those that have died as a result of a necrotic pathway because the dead cells will stain with both Annexin V-FITC and PI (see image). However, when apoptosis is measured over time, cells can be often tracked from Annexin V- FITC and PI negative (viable, or no measurable apoptosis), to Annexin V-FITC positive and PI negative (early apoptosis, membrane integrity is present) and finally to Annexin V- FITC and PI positive (end stage apoptosis and death). The movement of cells through these three stages suggests apoptosis. In contrast, a single observation indicating that cells are both Annexin V-FITC and PI positive, in of itself, reveals less information about the process by which the cells underwent their demise. For this reason, it is a good idea to analyze samples from multiple time points.

Applications/Dilutions

• Dilutions:
  • Flow (Cell Surface)
  • Flow Cytometry
  • Immunocytochemistry/Immunofluorescence
• Application Notes: Use in Flow cell surface reported in scientific literature (PMID: 23955790). Use the Control Cells provided to set up compensation and quadrants. The Control Cells are positive for both Annexin V-FITC and PI.
  The basal level of apoptosis and necrosis varies considerably within a give cell population. Even in the absence of induced apoptosis, most cell populations will contain a minor percentage of cells that are positive for apoptosis (Annexin V-FITC positive, PI negative) and dead, necrotic, or in the late stages of apoptosis (Annexin V-FITC positive, PI positive). Thus, an untreated cell population is used to define the basal level of apoptotic and dead cells.
  Determine the percentage of cells that have been induced to undergo apoptosis by subtracting the percentage of apoptotic cells in the untreated from the treated population. Since cell death is the eventual outcome of cells undergoing apoptosis, cells in the late stages of apoptosis will have a damaged membrane and stain positive for PI as well as for Annexin V-FITC.
  Consequently cells which have undergone necrosis are not distinguishable from those which have undergone apoptosis. Use in Immunocytochemistry/immunofluorescence reported in scientific literature (PMID: 25947082). Use in FLOW cytometry reported in scientific literature (PMID: 27448441).

Background

Apoptosis is the term that describes programmed cell death. It is believed to take place in the majority of animal and plant cells. It is a distinct event that triggers characteristic morphological and biological changes in the cellular life cycle. One of the early events that happens in the apoptotic pathway is the loss of plasma membrane asymmetry. In apoptotic cells, the membrane phospholipid phosphatidylserine (PS) is translocated from the inner to the outer leaflet of the plasma membrane, thereby exposing PS to the external cellular environment. Annexin V when labeled with a fluorescent tag, such as FITC, can be used with flow cytometry to measure this event. Annexin V is a 35-36 kDa Ca2+ dependent phospholipid-binding protein that has a high affinity for PS, and binds to cells with exposed PS.
