Immunofluorescence image of HeLa cell expressing a fusion protein of GFP-polypyrimidine tract binding protein showing the localization of the perinucleolar compartment (green area) at the periphery of the nucleolus (red region). The nuclear periphery is demarcated by immunolabeling of the nuclear lamina (blue).
