PI (4,5) P2 regulerer forskellige cellulære funktioner, men dens nanoskala organisation i cellen plasmamembranen er dårligt forstået. Ved mærkning PI (4,5) P2 med en tofarvet fluorescerende probe fusioneret til pleckstrin homologidomænet beskriver vi en ny tilgang til at studere PI (4,5) P2 rumlige fordeling i plasmamembranen på nanometerskala .
