The fluorescence kinetics of the nitrobenzoxadiazole (NBD) chromophore were studied at low concentrations in solvents with varying polarity and hydrogen-bonding donor strength. The emission decay was essentially single exponential in all solvents studied. While the absorption and fluorescence solvatochromism is

The synthesis, identification and characterization of neutral lipid analogs containing N-(7-nitro-2,1,3-benzoxadiazoi-4-yl)-aminocaproic acid are reported. The acyl-imidazole derivative of the fluorescent fatty acid was used to esterify L-alpha-glycerophosphorylcholine. Fluorescent phosphatidylcholines were converted to the corresponding diacylglycerols by phospholipase C digestion. Triacylglycerols
It is proposed that increased phospholipid unsaturation in membranes and perturbation by agents such as ethanol weaken interlipid hydrogen bonding involving water and that the process is independent of effects on lipid order. To investigate this, the rates of phospholipid

In order to study the endocytosis of membrane lipids during the development of neuronal polarity, we examined the internalization of a short acyl chain fluorescent derivative of ganglioside GM1, N-(6-(4-nitrobenz-2-oxa-1,3-diazole-7-yl)-aminohexanoyl)-GM1 (C6-NBD-GM1), in hippocampal neurons cultured at low density. C6-NBD-GM1 was
Live-cell imaging allows the in vivo analysis of subcellular localisation dynamics of physiological processes with high spatial-temporal resolution. However, only few fluorescent dyes have been custom-designed to facilitate species-specific live-cell imaging approaches in filamentous fungi to date. Therefore, we developed
Nitric oxide (NO) as a signal transporter in neurons, endothelial cells and in the immune system.
