Assay glutamate uptake fluorescent
WebCells are permeable. Rose Bengal is a polyhalogenated fluorescein derivative that can act as an effective inhibitor of glutamate uptake into synaptic vesicles (K(i) = 19 nM). Without affecting the H(up)-pumping ATPase, this vesicle Glu uptake inhibition is achieved. WebOct 19, 2024 · Reduced glutamate uptake is associated with excitotoxicity and oxidative damage. Furthermore, a return to basal levels of glutamate uptake in fish pretreated with melatonin could show up as antioxidant neuroprotection. In order to evaluate oxidative damage, we assessed the free radical formation through TBA-RS and DCFH oxidation …

WebSep 30, 2005 · The assay is based on direct incubation of mammalian cells with a fluorescent d-glucose analog 2- [N- (7-nitrobenz-2-oxa-1,3-diazol-4-yl) amino]-2-deoxy-D-glucose (2-NBDG) followed by flow cytometric detection of fluorescence produced by the cells. A series of experiments were conducted to define optimal conditions for this assay. WebMar 7, 2024 · The cystine/glutamate antiporter (xCT) is a crucial transporter that maintains cellular redox balance by regulating intracellular glutathione synthesis via cystine uptake. However, no robust and simple method to determine the cystine uptake activity of xCT is currently available. We have developed a method to measure the xCT activity via the …
WebMar 8, 2013 · After total protein determination by Bradford assay (Bio-Rad), 1μCi l - 3 H glutamate and 100 μ m non-labeled glutamate were mixed with Na + uptake buffer (total volume 275 μl) and then added into 25 μl of each synaptosome sample in 96-well multiscreen HTS filter plates (Millipore). WebHow the Assay Works Glutamate dehydrogenase uses glutamate and NAD+ to produce α-ketoglutarate and NADH. In the presence of NADH a pro-luciferin Reductase Substrate is converted by Reductase to luciferin that is then used by Ultra-Glo™ Recombinant Luciferase to produce light.
WebJun 14, 2005 · The fluorescent indicator protein for glutamate (FLIPE) consists of the glutamate/aspartate binding protein ybeJ from Escherichia coli fused to two variants of the green fluorescent protein. Three sensors with lower affinities for glutamate were created by mutation of residues peristeric to the ybeJ binding pocket.
