Introduction: Glycosylphosphatidylinositol (GPI) anchored proteins are common on the surfaces of eukaryotic cells. An example is alkaline phosphatase. Fluorescently Labelled Aerolysin (FLAER) is a bacterial toxin produced by the gram-negative bacterium Aeromonas hydrophila that binds naturally to GPI anchored proteins and utilizes them as receptors to cause cytotoxicity. FLAER has been used to discriminate the GPI deficient red blood cells in cases of paroxysmal nocturn...
