Figure 2.

(a) Linear regression curve MFE versus TRF values. MFE data calculated on sample analysed in Fig. 1; TRF sizes obtained from Mochida et al. 4 for Ramos and Daudi cells and from Jeyapalan et al. 5 for 1301 cells. In the graph, equation and coefficient of determination (R ²) of the curve are reported. (b) Images represent PNA probe emission of the three cell lines treated without Eth‐Br counterstaining to demonstrate different fluorescence patterns. Photomicrographs obtained using Olympus BX51 microscope equipped with a SPOT RT colour camera, objective 60× and Cy5 filter (Olympus U‐MWIY2).
