Photolytic uncaging
WebThe photolytic efficiency of a cage upon 2PE is quanti ed by its two-photon uncaging (2PU) cross-sections d u de ned as d u ¼ s 2F u; where s 2 is the two-photon absorption (2PA) cross-section (in GM) and F u the uncaging quantum yield.15 Until recently, the use of most cages described in the liter- WebDefine photolytic. photolytic synonyms, photolytic pronunciation, photolytic translation, English dictionary definition of photolytic. n.

WebApr 7, 2010 · Photolytic uncaging of compounds within the cytosol of cells is a powerful tool for cell biology, especially for investigating the signaling mechanism of cells . Photo … WebIn some cases, neuronal connectivity can be studied entirely using optical approaches by combining VSD imaging with a photolytic uncaging system. Recently genetically encoded voltage sensitive probes have been successfully developed. With this new technology, one would be able to characterize activity of a specific neuron at a high ...
WebJul 1, 2016 · In acute slices from C57BL/6 mice, we find that co-activation of presynaptic GABA receptors by photolytic uncaging of RuBi-GABA has a biphasic effect on EPSC amplitudes recorded from stellate cells. Synchronous and asynchronous EPSCs evoked within ∼100 ms of GABA uncaging were increased, while EPSCs evoked ∼300-600 ms … WebMay 1, 2007 · Ca(2+) rises evoked by photolytic uncaging of IP(3) showed the same distribution, suggesting that IP(3)-sensitive Ca(2+) stores are preferentially located in the soma and proximal dendrites. This distribution of metabotropic-mediated store release suggests that the neuromodulatory role of metabotropic receptor stimulation in BLA …
WebPrevious attempts of modifying the oNB group to improve the light-harvesting efficiency have usually led to decreased uncaging quantum yields, so the overall photolytic … WebMethods are available that can 'cage' neurotransmitters, precluding them from binding with receptors in the nervous system. They are thus rendered biologically inert until photolytic …
WebNov 15, 2010 · A series of recent reviews have extensively described the different caging groups 1 as well as the biological applications thereof. 2 Among the more recent outcomes related to this methodology is the two-photon (2P) uncaging process which induces a photolytic reaction with a remarkable spatial resolution, allowing to analyze cellular …
WebMay 11, 2024 · By using either photolytic uncaging of intracellular Ca 2+ (Figure 4—figure supplement 1) or Ca 2+ infusion (Figure 4), we have observed opposite effects if the curvature-mediating lipid components were applied intracellularly and found, in contrast to Zhang and Jackson, only a slight increase in the sustained rate of secretion with LPC … flannels warrantyWebNov 3, 2010 · Photolytic uncaging of glutamate in MB immediately following a single sucrose–odor pairing resulted in improved response to the odor alone 48 h later (eLTM) (Locatelli et al., 2005).
