DNA catalysts (also called DNA enzymes or deoxyribozymes), are synthetic DNAs with defined sequence that fold into 3-dimensional structures to bind substrates and accelerate chemical reactions. > more
Natural RNA Modifications
The chemical diversity of RNA is not limited to the four letters A, C, G, and U. Instead, natural RNA contains more than 150 different modified nucleotides, with diverse biological roles. > more
Fluorescent RNA Aptamers
Aptamers are synthetic DNAs or RNAs that fold into defined structures to bind desired ligands with high specificity and affinity. Fluorogenic aptamers bind small organic dyes to form fluorescent noncovalent RNA-dye complexes. > more
RNA as a catalyst
Ribozymes are generated in the laboratory by in vitro selection from libraries of random RNA sequences, for example to catalyze site-specific RNA labeling reactions. > more
Synthetic modified nucleotides are essential for biophysical chemistry of RNA folding. Spin-labeled nucleotides contain paramagnetic nucleotides that enable EPR and specific NMR experiments on RNA and RNA protein complexes. > more
Fluorescent nucleoside analogs
Fluorescent nucleotide analogs are incorporated into RNA by solid-phase synthesis. Conformational changes by folding or ligand binding are monitored by changes in fluorescence emission. > more
