MOESM8 of SELEX tool: a novel and convenient gel-based diffusion method for monitoring of aptamer-target binding

Additional file 8: Figure S7. Characterization of the binding of aptamer-profenofos and -atrazine by chasing diffusion. Concentration of Apt: 10 μM. Targets concentration: profenfos, 10 mM; atrazine, 20 mM; Diffusion time was 9 h at room temperature. Binding buffer only as a negative control.
