UDG and APE digestion of UO and UI nucleosomes. (A) Denaturing gels of UO and UI naked DNA and NuCPs after incubation with UDG and APE, each at 1 nM. Time is from 30 sec to 1 h and M is mock-treated. (B) Plot of the mean ± 1 SD (three independent experiments) of the percent DNA cut by 1 nM UDG and APE for UO DNA (solid line, •), UI DNA (dashed line, □), UO NuCP (solid line, ⋄), and UI NuCP (dashed line, ▵). Dotted line (×) represents nucleosome samples digested with 10 nM UDG and APE. (C) Plot of the mean ± 1 SD (three independent experiments) of the percent of DNA cut by 100 pM UDG and APE for UO DNA (solid line, □) and UI DNA (dashed line, □). (Inset) Representative gel for digestions of UO and UI naked DNA for times from 30 sec to 10 min.
