Fig. 1. Distribution of telomeric sequences, p43 and telomerase in the macronucleus of Euplotes before and after electroelution as described previously (Postberg et al., 2001). Telomeric sequences and telomerase were detected by FISH analysis, p43 by antibody staining. Arrows point to the replication band. (a) Distribution of telomeric sequences, p43 and telomerase in the macronucleus of Euplotes before electroelution. 1, telomeric sequences; 2, p43; 3, telomerase. (b) Distribution of telomeric sequences, p43 and telomerase in the macronucleus of Euplotes after electroelution. 1, telomeric sequences; 2, p43; 3, telomerase. Bar, 10 µm.
