Spectrofluorimetric Method for the Determination of Doxepin Hydrochloride in Commercial Dosage Forms
The primary role of glutathione transferase is to defend an organism from toxicities through catalyzing the reaction of glutathione (GSH) with potentially toxic compounds or metabolites to their chemically and biologically inert conjugates. The objective of the study was to develop a simple and sensitive spectrofluorimetric assay method for glutathione transferase using monobromobimane (MBB), a...
This study focuses on the spectrofluorimetric behaviour of a pharmaceutically and analytically important molecule 1-naphthoic acid in the presence of various surfactant solutions. Micellar solubilization is a powerful alternative for dissolving hydrophobic compounds in aqueous environment. Fluorescence and absorption spectroscopy are the two techniques used to monitor the micellar solubilizatio...
Um procedimento relativamente simples e sensível com detecção espectrofluorimétrica foi desenvolvido para a determinação de cistina e cisteína por sistema de injeção em fluxo com determinação seqüencial. Esse método é fundamentado na redução de Tl(III) com cisteína em meio ácido, produzindo o reagente fluorescente TlCl 3 2(λ ex = 227 nm, λ em = 419 nm). Antes da injeção, a solução da amostra fo...
The present study offers a new method based on CdSe quantum dots (QDs) for simultaneous separation and determination of trace levels of heparin (Hep) in human serum samples. In this technique, CdSe QDs perform two different functions in Hep analysis process. Mercaptoacetic acid-capped red CdSe QDs (λex=690 nm) are conjugated to Hep and the Hep-QD conjugation is then used as an extraction...
