The dual aptamer approach: rational design of a high-affinity FAD aptamer.
نویسندگان
چکیده
A design strategy for high-affinity aptamers of complex biomolecules is presented. We developed an RNA with FAD-binding properties by combining known ATP- and FMN-aptamers. Cooperative binding of FAD was shown by SPR spectroscopy and fluorescence assays. The strategy should be transferable to several other biomolecules.

Identification of Aptamer-Binding Sites in Hepatitis C Virus Envelope Glycoprotein E2
Hepatitis C Virus (HCV) encodes two envelope glycoproteins, E1 and E2. Our previous work selected a specific aptamer ZE2, which could bind to E2 with high affinity, with a great potential for developing new molecular probes as an early diagnostic reagents or therapeutic drugs targeting HCV. In this study, the binding sites between E2 and aptamer ZE2 were further explored. E2 was truncated to 15...
