WebAug 15, 2015 · Here we have developed a sensitive cancer cell amplified detection method which combined Au NPs enhanced electrochemiluminescence (ECL) of CdS nanocrystals (NCs) film, with isothermal circular amplification reaction of polymerase. WebThe CV (%) for the nine tissues revealed only 7% variation with Beacon detection, which suggested the detection reproducibility regardless of tissue heterogeneity and considerable variation in DNA yield. Both Beacon and TaqMan detection for DNA and RNA sequences of β-Actin with the same sample showed a similar result with an average ratio ...

WebNov 21, 2011 · The mature miR-21 DNA beacon ( A, 200 nM) or precursor miR-21 DNA beacon ( B, 200 nM) was incubated with the indicated concentrations of mature miR-21 RNA or pre-miR-21 RNA (60 min at 37°C). The relative fluorescence signal from each molecular beacon alone in PBS was used as a background measurement and … WebMolecular beacons are nucleic acid hybridization probes. They are designed to bind to target DNA sequences in regions, such as the rpoB, where resistance mutations are known to occur. Molecular beacons will fluoresce only when bound to their targets so that a mutation – even a single nucleotide substitution – will prevent fluorescence. download outlook app windows 1

WebHere we report a tweezer-like DNA nanodevice to actuate the activity of an enzyme/cofactor pair. A dehydrogenase and NAD (+) cofactor are attached to different arms of the DNA tweezer structure and actuation of enzymatic function is achieved by switching the tweezers between open and closed states. The enzyme/cofactor pair is spatially ... WebProtein detection plays an important role in biological and biomedical sciences. The immunoassay based on fluorescence labeling has good specificity but a high labeling cost. Herein, on the basis of G-triplex molecular beacon (G3MB) and thioflavin T (ThT), we developed a simple and label-free biosensor for protein detection.
