Fluorescent dyes specific for quadruplex DNA [PDF]

Nucleic Acids Research, 1998
Fluorescent dyes which are specific for duplex DNA have found a wide range of applications from staining gels to visualization of chromosomes. Porphyrin dyes have been found which are highly fluorescent in the presence of quadruplex but not duplex DNA. These dyes may offer a route to the specific detection of quadruplex DNA under biologically important

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Identification of groundwater microbes that decrease the concentration of the conservative tracer uranine

Heliyon
Fluorescent dyes are commonly used as conservative groundwater tracers to track the migration of water. Over- or underestimation of important parameters such as the water flow rate can occur if the concentration of a dye is changed by unexpected ...

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Engineering of near IR fluorescent albumin nanoparticles for in vivo detection of colon cancer

Journal of Nanobiotechnology, 2012
Background The use of near-infrared (NIR) fluorescence imaging techniques has gained great interest for early detection of cancer because water and other intrinsic biomolecules display negligible absorption or autofluorescence in this region.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Quantitative in vivo distribution of Cy5.5 fluorescent dye. [PDF]

, 2018
(A, B) The distribution of Cy5.5 fluorescent dye was determined by in vivo optical imaging at 24 hours after injection. The injection was performed at 7 days after SCI for rats with SCI (A for normal group, B for SCI group, n = 5 for each group).

Fluorescent, Prussian Blue-Based Biocompatible Nanoparticle System for Multimodal Imaging Contrast

Nanomaterials, 2020
(1) Background. The main goal of this work was to develop a fluorescent dye-labelling technique for our previously described nanosized platform, citrate-coated Prussian blue (PB) nanoparticles (PBNPs). In addition, characteristics and stability of the PB

Cobalt Detection Using Fluorescent Dye Layers

Engineering Proceedings, 2022
In this paper, we report the preliminary results regarding the use of fluorescent dye calcein (C30H26N2O13) as a sensor for the detection of cobalt levels in aqueous solutions.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
