SPP-GFP fusion protein expression in yeast as visualized by confocal microscopy. An aliquot of the yeast culture cell suspension overexpressing the fusion protein was placed onto a microscope slide to observe GFP fluorescence by microscopy. (A) Fluorescence from the control cells harboring only the vector. GFP fluorescence was not detected. (B) Transformation with HsSPP-GFP. (C) Transformation with AtSPP-GFP.
