Figure Lengend Snippet: Lane 1–4 (A–D) DNA cleavage reactions with 250 nM, 500 nM, 1.0 μM, and 2.5 μM test complex (A) Cu-Phen, (B) Cu-DPQ-Phen, (C) Cu-DPPZ-Phen, and (D) Cu-Terph, 400 ng superhelical pUC19 and 1 mM added Na-L-ascorbate incubated at 37°C for 30 min . Lanes 5–16 (A–D) DNA cleavage reactions in the presence of recognition elements, methyl green (MG), netropsin (Net), and [Co(NH 3 ) 6 ]Cl 3 (Co(III)), where 400 ng pUC19 was initially pre-treated with 8 μM of respective non-covalent binding control at 37° C for 45 min and then with 250 nM, 500 nM, 1 μM, and 2.5 μM test complex in the presence of 1 mM added Na-L-ascorbate at 37°C for 30 min.
Article Snippet: Reactions were carried out according to the following general procedure: in a total volume of 20 μL using 80 mM HEPES buffer (pH 7.2) with 25 mM NaCl, 1 mM Na-L-ascorbate, 400 ng superhelical pUC19 (NEB, N3041) and varying concentrations of test complex (250 nM, 500 nM, 1 μM and 2.5 μM).
