Fluorescently Labelled Aerolysin (FLAER) Labelling of Candida albicans Cells

In this protocol we describe a nonradiolabelled labelling of GPI anchor in Candida albicans. The method uses a fluorescent probe to bind specifically to GPI anchors so that the level of GPI-anchored proteins at the cell surface can be measured. The labelling does not need permeabilization of cells and can be carried out in vivo.
