Additional file 9: Figure S8. Generation and characterization of aptamers against DDA. A, SELEX protocol to isolation of aptamers bound to DDA; B, Enrichment of the dynamic libraries in SELEX rounds by real-time PCR; C and D, characterization of the affinity (C) and selectivity (D) of one aptamer against DDA by using SYBR Green I assay.
