Aptamer Rivalry [PDF]

open access: yesChemistry & Biology, 2002
A controllable, intracellular RNA aptamer could be an invaluable therapeutic or discovery reagent. A report published in this journal shows that aptamer behavior can be regulated by a small molecule, paving the way for the development of more sophisticated ligand-regulated aptamers.

Aptamers [PDF]

open access: yes, 2018
Aptamers are in vitro selected oligonucleotides capable of specific, high-affinity binding to a wide variety of target molecules. These features enable their application in diagnostics, therapeutics, targeted delivery, fluorescence imaging, and biosensing.

Methods for Improving Aptamer Binding Affinity

open access: yesMolecules, 2016
Aptamers are single stranded oligonucleotides that bind a wide range of biological targets. Although aptamers can be isolated from pools of random sequence oligonucleotides using affinity-based selection, aptamers with high affinities are not always ...

Aptamers: A Feasible Technology in Cancer Immunotherapy

open access: yesJournal of Immunology Research, 2016
Aptamers are single-chained RNA or DNA oligonucleotides (ODNs) with three-dimensional folding structures which allow them to bind to their targets with high specificity.

Selecting Molecular Recognition. What Can Existing Aptamers Tell Us about Their Inherent Recognition Capabilities and Modes of Interaction?

open access: yesPharmaceuticals, 2012
The use of nucleic acid derived aptamers has rapidly expanded since the introduction of SELEX in 1990. Nucleic acid aptamers have demonstrated their ability to target a broad range of molecules in ways that rival antibodies, but advances have been very ...

DNA Aptamers against Taiwan Banded Krait α-Bungarotoxin Recognize Taiwan Cobra Cardiotoxins

open access: yesToxins, 2016
Bungarus multicinctus α-bungarotoxin (α-Bgt) and Naja atra cardiotoxins (CTXs) share a common structural scaffold, and their tertiary structures adopt three-fingered loop motifs. Four DNA aptamers against α-Bgt have been reported previously.

Development of DNA aptamer selection approach based on membrane ultrafiltration of aptamer/target complex

open access: yesActa Biomedica Scientifica, 2022
Background. Aptamers are small single-stranded DNA or RNA molecules that have an affinity for a specific target molecule. The main method of aptamers construction is the technology of systematic evolution of ligands with exponential enrichment (SELEX ...

Role of Exosomes in Cancer and Aptamer-Modified Exosomes as a Promising Platform for Cancer Targeted Therapy

open access: yesBiological Procedures Online
Exosomes are increasingly recognized as important mediators of intercellular communication in cancer biology. Exosomes can be derived from cancer cells as well as cellular components in tumor microenvironment.
