Nuclear Magnetic Resonance (NMR) Spectroscopy is a powerful technique for studying aptamer structure and function. Important information about ligand binding and how binding affects aptamer structure can be obtained relatively quickly using 1H NMR spectra focused on the imino resonances. Here we summarise some practical information for preparing aptamer samples for NMR analysis, designing experiments, and interpreting results, with an emphasis on aptamer-small molecule interactions.

KEYWORDS: Aptamers, Nuclear Magnetic Resonance Spectroscopy, folding, small molecule interactions
