A general strategy to develop fluorogenic polymethine dyes for bioimaging

Pablo Rivera Fuentes, Annabell Martin

Fluorescence imaging is an invaluable tool to study biological processes and further progress depends on the development of advanced fluorogenic probes that reach intracellular targets and label them with high specificity. Excellent fluorogenic rhodamine d ...

Photoactivatable Silicon Rhodamines for Super-Resolution Microscopy

Michelle Susanne Frei

Fluorescence microscopy is the method of choice to monitor dynamic processes in living cells due to its non-invasive nature. A variety of different fluorophores and labeling systems are currently used to selectively visualise structures or biomolecules of ...

Azacyanine dyes and use thereof

Riccardo Sinisi, Elena Goun, Alma Rosa Morales Morales

The application provides fluorescent dyes, which are cyanine dyes that incorporate additional aza moieties in the indolenium heterocycles and/or in the methine chains connecting them. Symmetrical and unsymmetrical chemically reactive azacyanine dyes are de ...

Photoactivatable Fluorescent Protein mEos2 Displays Repeated Photoactivation after a Long-Lived Dark State in the Red Photoconverted Form

Aleksandra Radenovic, Paolo Annibale, Marco Scarselli

Illumination with 405 nm light can recover the emission for single green fluorescent protein (GFP) mutants that have gone into a long-lived dark state. The reported behavior is the standard for the reverse photoswitchable protein Dronpa and its mutants. Ho ...

Photoactivatable Probes for Protein Labeling

Sambashiva Banala

Over the last decade, several protein tags have been developed for the specific and covalent labeling of fusion proteins with small organic probes. Among them, SNAP-tag has been used in many applications such as live cell imaging, protein microarrays and t ...

3 W of 650 nm red emission by frequency doubling of wafer-fused semiconductor disk laser

Elyahou Kapon, Alexandru Mereuta, Alexei Sirbu

3 W at genuine red wavelength of 650 nm has been achieved from a semiconductor disk laser by frequency doubling. An InP based active medium was fused with a GaAs/AlGaAs distributed Bragg reflector resulting in an integrated monolithic gain mirror. 6.6 W of ...

Coumarin-based luminescent ligand that forms helicates with dicationic metal ions

The potentially hexadentate ligand L, which contains two terminal coumarin fluorophores, forms dinuclear double-stranded helicates with dicationic metal ions, giving species of the generic form M2L2. In solution the free ligand was fluorescent with e ...

Design of an endoscopic optical reference to be used for autofluorescence bronchoscopy with a commercially available diagnostic autofluorescence endoscopy (DAFE) system

Georges Wagnières, Tanja Gabrecht, Blaise Lovisa, François André Borle

We present the design of a sterilizable optical reference to characterize and quantify the inter-patient variations in tissue autofluorescence during autofluorescence bronchoscopy with Richard Wolf's diagnostic autofluorescence endoscopy (DAFE) system. The ...

Photoimmunodiagnosis with antibody-fluorescein conjugates: In vitro and in vivo preclinical studies

Hubert van den Bergh, Georges Wagnières, André Châtelain

The use of dyes has been helpful for the photodiagnosis of small cancers accessible to endoscopic examn. An important limiting factor of this technol. is that the presently used fluorescent dye mixt. has a relatively poor capacity to accumulate preferentia ...

Antibody-fluorescein conjugates for photoimmunodiagnosis of human colon carcinoma in nude mice

Hubert van den Bergh, Georges Wagnières

To improve the detectability of tumors by light-induced fluorescence, the use of monoclonal antibodies (MoAb) as carriers of fluorescent molecules was studied. As a model for this approach, the biodistribution of an anticarcinoembryonic antigen (CEA) MoAb ...
