Molecular beacons

open access: yesCurrent Opinion in Chemical Biology, 2004
This opinion covers the field of molecular beacons (MBs), in which nucleic acids are molecularly engineered to have unique functions for the investigation of biomolecules. Molecular beacons have been used in a variety of formats, and this review discusses four: first, in vitro RNA and DNA monitoring; second, biosensors and biochips based on MBs; third,

MicroRNA Detection Using a Double Molecular Beacon Approach: Distinguishing Between miRNA and Pre-miRNA [PDF]

open access: yes, 2017
MicroRNAs (miRNAs) are small, noncoding RNAs that post-transcriptionally regulate gene expression and are recognized for their roles both as modulators of disease progression and as biomarkers of disease activity, including neurological diseases, cancer,

In vitro selection of molecular beacons [PDF]

open access: yesNucleic Acids Research, 2003
While molecular beacons are primarily known as biosensors for the detection of nucleic acids, it has proven possible to adapt other nucleic acid binding species (aptamers) to function in a manner similar to molecular beacons, yielding fluorescent signals only in the presence of a cognate ligand.

Design of a molecular beacon PNA [PDF]

open access: yesNucleic Acids Symposium Series, 2002
We have designed a novel dual-labeled PNA oligomer, having both a fluorescent dye and a quencher, by utilizing key compounds 1 and 2. We showed that the designed dual-labeled PNA oligomer works as a molecular beacon PNA. We also investigated the optimization of a stem-loop structure which can supersensitize the function as a molecular beacon PNA.

PNA-induced assembly of fluorescent proteins using DNA as a framework [PDF]

open access: yes, 2013
Controlled alignment of proteins on molecular frameworks requires the development of facile and orthogonal chemical approaches and molecular scaffolds. In this work, protein−PNA conjugates are brought forward as new chemical components allowing efficient

tmRNA - a novel high-copy-number RNA diagnostic target - its application for Staphylococcus aureus detection using real-time NASBA [PDF]

open access: yes, 2009
A real-time nucleic acid sequence-based amplification assay, targeting tmRNA, was designed for the rapid identification of Staphylococcus aureus. The selectivity of the assay was confirmed against a panel of 76 Staphylococcus strains and species and 22 ...

Genomic and phenotypic evolution of Escherichia coli in a novel citrate-only resource environment

open access: yeseLife, 2020
Evolutionary innovations allow populations to colonize new ecological niches. We previously reported that aerobic growth on citrate (Cit+) evolved in an Escherichia coli population during adaptation to a minimal glucose medium containing citrate (DM25 ...
