Structure–Activity Relationship Study of a Potent α‐Thrombin Binding Aptamer Incorporating Hexitol Nucleotides [PDF]
AbstractThe replacement of one or more nucleotide residues in the potent α‐thrombin‐binding aptamer NU172 with hexitol‐based nucleotides has been devised to study the effect of these substitutions on the physicochemical and functional properties of the anticoagulant agent.

Mature miRNAs form secondary structure, which suggests their function beyond RISC. [PDF]
The generally accepted model of the miRNA-guided RNA down-regulation suggests that mature miRNA targets mRNA in a nucleotide sequence-specific manner.

Identification of Allosteric Nucleotide Sites of Tetramethylrhodamine-Labeled Aptamer for Noncompetitive Aptamer-Based Fluorescence Anisotropy Detection of a Small Molecule, Ochratoxin A [PDF]
Aptamer-based fluorescence anisotropy (FA) assay combines the advantages of affinity aptamers in good stability, easy generation, and facile labeling and the benefits of FA in homogeneous analysis, such as robustness, simplicity, and high reproducibility.

Design and clinical developments of aptamer-drug conjugates for targeted cancer therapy
Background Aptamer has been called “chemical antibody” which displays the specific affinity to target molecules compared to that of antibodies and possesses several therapeutic advantages over antibodies in terms of size, accessibility to synthesis, and ...

Application of Aptamers in Virus Detection and Antiviral Therapy
Viral infections can cause serious diseases for humans and animals. Accurate and early detection of viruses is often crucial for clinical diagnosis and therapy. Aptamers are mostly single-stranded nucleotide sequences that are artificially synthesized by
