Cell Meter(TM) Phosphatidylserine Apoptosis Assay Kit *Optimized Red Fluorescence for Flow Cytometry

The Cell Meter(TM) 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 sensor that specifically binds PS. The PS sensor used in this kit has red fluorescence upon binding to membrane PS. This particular assay kit is optimized to monitor cell apoptosis using a flow cytometer at Cy5 channel (red fluorescence).
