FIG. 6.
Interference footprinting assays performed with primers in which the number and distribution of telomeric repeats have been varied. Formic acid (FA) and KMnO4 interference assays were carried out as described in the legends to Fig. 3 and 4. (A) Formic acid (2.5%) assays and 0.10 mM KMnO4 assays of oligo tel6. (B) Formic acid (4%) assays and 0.12 mM KMnO4 assays of oligo tel7. (C) Formic acid (3%) assays and 0.15 mM KMnO4 assays of oligo tel8. In these assays, bands corresponding to residues 32 to 35 could not be resolved and hence were not quantitated.
