Figure 5

Effect of azobenzene linker length and the number of homopyrimidine bases of PNA on complex formation with complementary ssDNA. (A) Each lane contains 100 nM of DNA1. Each lane from the left side contains no PNA, 200 nM of PNA1, PNA2, PNA6, PNA8, and PNA15. Each DNA and PNA were incubated in 10 mM sodium phosphate buffer (pH 6.0) at 25 °C for 10 min. Gel mobility shift assays of PNA/DNA complexes were performed using 15% non-denaturing polyacrylamide gels. (B) Quantitative band-intensity analysis of DNA and DNA/PNA complexes in Figure 5.
