We present here the application of a novel assay that measures the absolute amount of PS externalized on the surface of cells. While based on the same annexin binding principle as the fluorescent flow cytometry assay, we use paramagnetic iron as the ultimate reporter molecule, establishing a linear relationship between signal amplitude and amount of PS on the cell surface, allowing a quantitative assay of PS externalization over a wide dynamic range. The application of this technique, alone and in concert with the PS oxidation method presented in the previous chapter, will greatly aid in studying the mechanistic connection between lipid peroxidation and translocation events during apoptosis.
