Stopped-flow CD kinetic traces for Amb-ctDNA (closed circles) and Ambochlorin (Amb)-ctDNA-H1 (open circles) binding interactions. The solutions were mixed in a 1:1 volume ratio. The circular dichroism (CD) signals of ctDNA and ctDNA-H1 (1.3×10-4 mM) were enhanced upon binding to Amb (0.07 mM). The first-order exponential decay model was applied to fit the raw data
