The fluorescence was due to the protein hrp36 conjugated to red-fluorescent AlexaFluor647, which was microinjected into the cytoplasm. After transport into the nucleus, hpr36 was incorporated into nascent RNA-particles, such that active transcription sites were marked. The brighter oval region in the image center is the cell nucleus. The .
