Application Notes
Suggested Staining Protocol: Wash cells twice in cold PBS; remove the PBS from the cell pellet after each wash.
Resuspend cells in cold 1X binding buffer to a concentration of 1 x 107 cells/mL.
Add 100 uL of cells (1 x 106) to each labeled tube.

Gently vortex each tube and incubate for 15 minutes on ice, protected from light.
Without washing, add 300 uL of cold 1X binding buffer to each tube.
Analyze by flow cytometry by gating on viable cells by light scatter.

Characterization
To insure lot to lot consistency, each batch of product is tested by flow cytometry to conform with the characteristics of a standard reference reagent.
Warning
Reagents contain sodium azide which is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.
Preparation and Storage
Annexin V-FITC: is supplied as 100 tests in 1.0 mL PBS/NaN3. Store at 2-8 degree C.; protect from light.

This is a recombinant protein that is produced in eukaryotic cells
A number of changes in cell structure occur during apoptosis. One major change is the loss of membrane phospholipid asymmetry, with translocation of phosphatidylserine (PS) from the inner leaflet of the phospholipid bilayer to the external surface.1 Annexin V (Mr 36-kDa), a member of the annexin family of calcium-dependent phospholipid binding proteins, has a high affinity for phosphatidylserine (PS)-containing phospholipid bilayers.2,3. When PS is exposed on the extracellular face of a cell membrane, Annexin V binds with an affinity of approximately 7 nM4. Fluorochrome-conjugated Annexin V can be used to monitor changes in cell membrane phospholipid asymmetry,5-8 thereby providing a convenient tool for detection of apoptotic cells.
Annexin V-FITC is a labeled Annexin V that can be used to evaluate subpopulations of cells along the apoptotic pathway without counterstaining with propidium iodide or other DNA dyes. Analysis is performed on a flow cytometer equipped with a 488 nm argon laser and gated on viable cells by light scatter (see flow histograms below). Alternatively, the cells can be examined by fluorescence microscopy.

Researchers should empirically determine the suitability of the Aposcreen Annexin V for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Aposcreen Annexin V, Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
