Phosphatidylserine Apoptosis Assay Kit (red fluorescence for microplate readers)
Description
Cell Meter? Phosphatidylserine Apoptosis Assay Kit *Red Fluorescence Optimized for Microplate Readers*. 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 sensor that specifically binds PS. This kit uses our proprietary fluorescent small molecule-based Apopxin? PS sensor that specifically binds PS with affinity much higher than Annexin V (Kd < 10 nM). It has red fluorescence upon binding to membrane PS. It can be used in the formats of microplate, microscope and flow cytometer while most of other commercial apoptosis assay kits are only used with either microscope or flow cytometry platform.
