Fluorescent nucleic acid base analogues.
The use of fluorescent nucleic acid base analogues is becoming increasingly important in the fields of biology, biochemistry and biophysical chemistry as well as in the field of DNA nanotechnology. The advantage of being able to incorporate a fluorescent probe molecule close to the site of examination in the nucleic acid-containing system of interest with merely a minimal perturbation to the na...
متن کاملFluorescent nucleobase analogues for base–base FRET in nucleic acids: synthesis, photophysics and applications
Förster resonance energy transfer (FRET) between a donor nucleobase analogue and an acceptor nucleobase analogue, base-base FRET, works as a spectroscopic ruler and protractor. With their firm stacking and ability to replace the natural nucleic acid bases inside the base-stack, base analogue donor and acceptor molecules complement external fluorophores like the Cy-, Alexa- and ATTO-dyes and ena...
متن کاملElectronic transition moments of 6-methyl isoxanthopterin—a fluorescent analogue of the nucleic acid base guanine
Fluorescent nucleic acid base analogues are important spectroscopic tools for understanding local structure and dynamics of DNA and RNA. We studied the orientations and magnitudes of the electric dipole transition moments (EDTMs) of 6-methyl isoxanthopterin (6-MI), a fluorescent analogue of guanine that has been particularly useful in biological studies. Using a combination of absorption spectr...
متن کاملPhotophysical and structural properties of the fluorescent nucleobase analogues of the tricyclic cytosine (tC) family.
Fundamental insight into the unique fluorescence and nucleobase-mimicking properties of the fluorescent nucleobase analogues of the tC family is not only vital in explaining the behaviour of these probes in nucleic acid environments, but will also be profitable in the development of new and improved fluorescent base analogues. Here, temperature-dependent fluorescence quantum yield measurements ...
متن کاملNucleic acid fluorescent probes for biological sensing.
Nucleic acid fluorescent probes are playing increasingly important roles in biological sensing in recent years. In addition to the conventional functions of single-stranded DNA/RNA to hybridize with their complementary strands, affinity nucleic acids (aptamers) with specific target binding properties have also been developed, which has greatly broadened the application of nucleic acid fluoresc...
