Figure 4. CD spectra of λ-DNA and different bDNA structures with and without LaCl3.

Figure 4

All DNA samples showed typical B-DNA conformation and after addition of LaCl3 condensation of DNA was noticed in all (a,b,d–f) except US2 bDNA. A clear B-Z transition was observed only with US2 at ≥5 mM concentration (c).
