We describe a highly sensitive CE with laser-induced fluorescence (LIF) detection for the analysis of N-linked oligosaccharides in glycoproteins using rhodamine 110 as a fluorescence derivatization reagent. One CE separation is performed using a fused-silica capillary and neutral pH buffer conditions and allows for the separation of sialo-oligosaccharides(More)
The purpose of this study was to examine the effects of stress and the role of locally infused anxiogenic-like neuropeptides galanin, CCK-8, vasopressin, substance P and neurokinin A, and anxiolytic-like peptides NPY, nociceptin/orphanin FQ, somatostatin and neurotensin, on modulation of noradrenaline (NA) and cAMP efflux monitored simultaneously by(More)
The neuropeptide galanin is co-localized with histamine in subpopulations of neurons in the tuberomammillary nucleus suggesting its involvement in modulating histaminergic neurotransmission. The purpose of the present study was to investigate, by use of microdialysis, the effects of local intraparenchymal (combined infusion and microdialysis probe), and(More)
Rhodamine 110 (Rho110) has been used in the highly sensitive analysis of monosaccharides, as it reacts with the reducing carbonyl group of the saccharides. The monosaccharide derivatives were investigated by capillary electrophoresis with laser-induced fluorescence detection. The derivatization was performed at 90 degrees C for 30 min for all(More)
The effects of the water extract of Sinomeni Caulis et Rhizoma (SCR-WE) and its major constituents, sinomenine (SIN) and magnoflorine (MAG), on moderate hemolysis induced by lysophosphatidylcholine (LPC) were investigated in rat erythrocytes and compared with the anti-hemolytic effects of lidocaine (LID) and propranolol (PRO) as reference drugs. LPC caused(More)
6-Rhodamine B amine functions as a highly sensitive fluorescence derivatization reagent for mono- and oligosaccharides; it reacts with the reducing end of saccharides under acidic conditions. The fluorescent derivatives of five monosaccharides can be separated within 25 min by reversed-phase liquid chromatography with isocratic elution. The detection limits(More)
