Cell Meter� Annexin V Binding Apoptosis Assay Kit *Orange Fluorescence Optimized for Flow Cytometry* Cat # 22825 Storage F/D/L (see storage codes below) Unit Size 1 kit Ex (nm) 554 Em (nm) 578 Our Cell Meter� assay kits are a set of tools for monitoring cell viability. There are a variety of parameters that can be used for monitoring cell viability. This particular kit is designed to monitor cell apoptosis through measuring the translocation of phosphatidylserine (PS). In apoptosis, PS is transferred to the outer leaflet of the plasma membrane. The appearance of phosphatidylserine on the cell surface is a universal indicator of the initial/intermediate stages of cell apoptosis and can be detected before morphological changes can be observed. This kit uses a fluorescent Annexin V that specifically binds PS. Annexin V conjugates have been demonstrated to selectively bind PS. This particular assay kit is optimized to monitor cell apoptosis using a flow cytometer with the Cy3 filter set.
