Related Product Information for Annexin V-Fluorescein Apoptosis assay kit
Description: Chicken Annexin V-Fluorescein Apoptosis Assay Kit provides a proven method for quickly and easily distinguishing two populations of dying cells from viable cells using recombinant fluorescein-conjugated Chicken Annexin V and Propidium Iodide (PI). These cells will become dually labeled with Annexin V-Fluorescein (green fluorescence) and Propidium Iodide (red fluorescence). Results can be analyzed via flow cytometer.
Background: Annexin V is a member of a calcium and phospholipid binding family of proteins with vascular anticoagulant activity. Results from in vitro experiments indicate that it may play a role in the inhibition of blood coagulation by competing for phosphatidylserine (PS) binding sites with prothrombin. In healthy cells, PS is usually kept in the inner-leaflet (the cytosolic side) of the cell membrane. When a cell undergoes apoptosis, one of the earliest detectable indicators is the loss of membrane asymmetry. No longer restricted to the cytosolic part of the membrane, PS is translocated to the outer-leaflet and becomes exposed on the surface of the cell.
Chicken Annexin V-Fluorescein Apoptosis Assay Kit provides a proven method for quickly and easily distinguishing two populations of dying cells from viable cells using recombinant fluorescein-conjugated Chicken Annexin V and Propidium Iodide (PI). Cells with intact cell membranes and surface-exposed PS, a prominent feature of apoptosis, will stain positive for Annexin V-Fluorescein. PI is included in the kit to identify dying, later stage apoptotic cells which have lost plasma membrane integrity. These cells will become dually labeled with Annexin V-Fluorescein and Propidium Iodide (green and red fluorescence). Live non-apoptotic cells with intact plasma membranes will exclude PI and will remain unstained by the Annexin V-Fluorescein probe, assuming no treatment or cell cycle-associated event temporarily exposes the normally internalized, negatively charged PS entity. The kit also includes a specially formulated, calcium-based binding buffer which is required for Annexin V binding to occur. Analyze results using a flow cytometer.

Product Notes
The Annexin V-Fluorescein Apoptosis (Catalog #AAA52755) is an Assay Kit and is intended for research purposes only. The product is available for immediate purchase. AAA Biotech's Annexin V-Fluorescein Apoptosis can be used in a range of immunoassay formats including, but not limited to, FCM/FACS (Flow Cytometry). Researchers should empirically determine the suitability of the Annexin V-Fluorescein Apoptosis 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 "Annexin V-Fluorescein Apoptosis, Assay Kit" 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
