Data analysis of GFP-18E6 level in 293T and MCF-7 cells. The expression level of GFP and GFP-18E6 are examined by fluorescence intensity dynamically. One hundred cells are examined for each plasmid from 20 random fields. The N/(N+C) indicates fluorescence intensity ratio of GFP fusion protein in nuclei (N) to it in both nuclei and cytoplasm (N+C).
