Fig. 1From: Characterization of DNA aptamers generated against the soft-shelled turtle iridovirus with antiviral effectsSELEX isolated eight aptamers that specifically targeted STIV particles. a Binding to STIV was enhanced in the higher selected pools, as demonstrated by ELISA. b Cluster analysis of the selected aptamers. c Secondary structures of aptamers QA-36, QA-92, QA-9, and QA-12. The stabilities of aptamer secondary structures were calculated as the free energy (ΔG)Back to article page
