Continuously tunable nucleic acid hybridization probes. [PDF]
Nat Methods, 2015 In silico-designed nucleic acid probes and primers often do not achieve favorable specificity and sensitivity tradeoffs on the first try, and iterative empirical sequence-based optimization is needed, particularly in multiplexed assays. We present a novel, on-the-fly method of tuning probe affinity and selectivity by adjusting the stoichiometry of ...

Activation of enzymatic catalysis via nucleic acid hybridization affords synergistic coupling of specificity, potency, and signal amplification [PDF]
Nature CommunicationsIn this work, we establish the use of nucleic acid hybridization to program the activation of catalysis in enzymes. We do this via “thiol switching”, using thiolated oligonucleotides: a protein is inactivated by conjugation to an oligonucleotide via a ...

Optimizing the specificity of nucleic acid hybridization. [PDF]
Nat Chem, 2012 The specific hybridization of complementary sequences is an essential property of nucleic acids, enabling diverse biological and biotechnological reactions and functions. However, the specificity of nucleic acid hybridization is compromised for long strands, except near the melting temperature. Here, we analytically derived the thermodynamic properties

Colorimetric Detection of Ehrlichia Canis via Nucleic Acid Hybridization in Gold Nano-Colloids [PDF]
Sensors, 2014 Canine monocytic ehrlichiosis (CME) is a major thick-bone disease of dog caused by Ehrlichia canis. Detection of this causal agent outside the laboratory using conventional methods is not effective enough. Thus an assay for E.
