WebFLAER is used in a flow cytometry test to diagnose paroxysmal nocturnal hemoglobinuria (PNH). FLAER is produced by labeling an inactive variant of the protein proaerolysin with Alexafluor® 488 succinimidyl ester. The reagent binds selectively to cell surface GPI-anchored proteins, , but will not bind to PNH cells without having that anchor.
