Figure 5: Temperature versus 1 ΔAA(max) profiles of the duplexes formed between the modified (7X) and unmodified (7A) oligonucleotides with the DNA oligonucleotides 10C and 10T in the presence and absence of Pd2+; [oligonucleotides] = 3.0 μM, [K2PdCl4] = 0/3.0 μM, scan range 220–320 nm; I(NaClO4) = 0.1 mol L−1; pH = 7.4.
