Web6 gen 2024 · RB005 is a 31-nucleotide RNA aptamer synthesized using chemically modified nucleotides to confer serum stability to the aptamer (Figure 1a). The majority of ribose sugars are modified with 2′-fluoro or 2′-O-methyl groups to enhance nuclease resistance and eliminate the inherent immunogenicity of unmodified RNA. WebThe thrombin binding aptamer (TBA) is a promising nucleic acid-based anticoagulant. We studied the effects of chemical modifications, such as dendrimer Trebler and NHS carboxy group, on TBA with respect to its structures and thrombin binding affinity. The two dendrimer modifications were incorporated into the TBA at the 5′ end and the NHS carboxy group …
