The laser dye rhodamine 123 is shown to be a specific probe for the localization of mitochondria in living cells. By virtue of its selectivity for mitochondria and its fluorescent properties, the detectability of mitochondria stained with rhodamine 123 is significantly improved over that provided by conventional light microscopic techniques. With the use of rhodamine 123, it is possible to dete...

Rhodamine B based fluorescence thermometry is commonly used in microfluidics to measure fluid temperatures in microchannels. Notable absorption of Rhodamine B into PDMS channel walls, however, causes difficulties in obtaining accurate temperature measurements due to a steady increase in the overall fluorescent signal. A simple and effective technique is reported that removes the fluorescent sig...

Fluorogenic supramolecular complexes formed between tubular-shaped pyrenyl-β-cyclodextrins and glyco-rhodamine are determined to respond to a selective lectin with 'turn-on' fluorescence with excellent selectivity over a range of competing species.

Equilibrium atomic geometries of rhodamine 6G (R6G) dye molecule dimers are studied using density-functional theory. Electron-energy structure and optical properties of R6G H and J dimers are calculated using the generalized gradient approximation method with ab initio pseudopotentials. Our theory predicts substantial redshifts or blueshifts of the optical absorption spectra of R6G dye molecule...

A new probe for Cu(2+) based on the Cu(2+)- induced reversible ring-opening mechanism of the rhodamine spirolactam was described. It displayed a highly selective and sensitive "turn-on" fluorescent and colorimetric response toward Cu(2+).

Background. Magical thinking, a sign of schizotypy, is accompanied by a decrease in the strength of left hemisphere language dominance and by an inattention towards the right side of space ("pseudoneglect"). We set out to explore whether it is also associated with a pseudoneglect in imagined space. Material and methods. Forty healthy right-handed adults were asked to imagine the contours of the...

The presented data are related to the research article entitled "Characterization of the IPEC-J2 MDR1 (iP-gp) cell line as a tool for identification of P-gp substrates" by Ozgur et al. (2017) [1]. This data report describes the challenges of investigating the concentration-dependent transport of P-glycoprotein (P-gp) substrates with relatively low aqueous solubility. Thus, we provide solubility...

Mitochondria of early Drosophila embryos were observed with a transmission electron microscope and a fluorescent microscope after vital staining with rhodamine 123, which accumulates only in active mitochondria. Rhodamine 123 accumulated particularly in the posterior pole region in early cleavage embryos, whereas the spatial distribution of mitochondria in an embryo was uniform throughout cleav...
