Table 2. Analysis of the binding of E2 on DNA containing all 4 four BS sites.
DNA (100 ng) was incubated with 150 ng of E2 and prepared as described in Materials and Methods. ATP, KCl or DTT were included in the reaction buffer as indicated (first column). After scoring several hundred E2-DNA complexes (second column), the statistical analysis of the complexes observed is as follows: protein-free DNA (third column), DNA with a single E2 dimer (fourth column), multiple dimers on DNA (each located at a specific BS site) (fifth column), looped DNA (sixth column).
| E2 on E2BS | n | ![]() |
|||
|---|---|---|---|---|---|
| w/ATP | 301 | 16% | 57% | 0% | 27% |
| w/o ATP | 300 | 48% | 41% | 0% | 11% |
| w/DTT | 301 | 7% | 45% | 23% | 25% |
| w/KCI | 262 | 38% | 38% | 21% | 3% |
