DNAzyme Hybridization, Cleavage, Degradation and Sensing in Undiluted Human Blood Serum
Zhou, Wenhu; Chen, Qingyun; Huang, Po-Jung Jimmy; Ding, Jinsong; Liu, Juewen (American Chemical Society, 2015-04-07)RNA-cleaving DNAzymes provide a unique platform for developing biosensors. However, a majority of the work has been performed in clean buffer solutions, while the activity of some important DNAzymes in biological sample ... -
A New Na+-Dependent RNA-Cleaving DNAzyme with over 1000-fold Rate Acceleration by Ethanol
Zhou, Wenhu; Saran, Runjhun; Chen, Qingyun; Ding, Jinsong; Liu, Juewen (Wiley, 2016-01-15)Enzymes working in organic solvents are important for analytical chemistry, catalysis, and mechanistic studies. Although a few protein enzymes are highly active in organic solvents, little is known regarding nucleic ... -
Searching for a DNAzyme version of the leadzyme
Saran, Runjhun; Chen, Qingyun; Liu, Juewen (Springer, 2015-10-12)The leadzyme refers to a small ribozyme that cleaves a RNA substrate in the presence of Pb2+. In an optimized form, the enzyme strand contains only two unpaired nucleotides. Most RNA-cleaving DNAzymes are much longer. Two ...
