Binding affinities (Kd values) of the initial random ssDNA library and the pools after CE-SELEX selection for VEGF. Kd values were obtained by both FP and ACE. Error bars represent 95% confidence intervals. Affinity of the initial random ssDNA library is an estimate of the minimum value, limited by the highest available VEGF concentration. Kd values of pool 3 (by FP and ACE) and pool 6 (by ACE) were not measured due to insufficient quantity of ssDNA produced in these rounds of selection.
