An ultrasensitive chemical method for polysialic acid analysis.
An ultrasensitive method for analysis of polysialic acid (polySia) chains, using fluorescence-assisted high-performance liquid chromatography was developed. The new method is a substantial improvement of our earlier method in which the reducing terminal Sia residues of a homologous series of oligo/polySia hydrolytically released during derivatization reaction were simultaneously labeled with a ...
متن کاملUltrasensitive chemical analysis by Raman spectroscopy.
In the Raman effect, incident light is inelastically scattered from a sample and shifted in frequency by the energy of its characteristic molecular vibrations. Since its discovery in 1927, the effect has attracted attention from a basic research point of view as well as a powerful spectroscopic technique with many practical applications. The advent of laser light sources with monochromatic phot...
متن کاملAn Improved GC Method for Rapid Analysis of Valproic Acid in Human Plasma Without Derivatization
A simple, reproducible and rapid gas chromatographic method for precise determination of valproic acid (VPA) in human plasma has been developed. Total time for sample preparation and GC analysis is less than 45 min. After plasma protein precipitation, VPA was extracted into chloroform with suitable recovery. By using Stabilwax®<span styl...
متن کاملAn ultrasensitive photoelectrochemical nucleic acid biosensor
A simple and ultrasensitive procedure for non-labeling detection of nucleic acids is described in this study. It is based on the photoelectrochemical detection of target nucleic acids by forming a nucleic acid/photoreporter adduct layer on an ITO electrode. The target nucleic acids were hybridized with immobilized oligonucleotide capture probes on the ITO electrode. A subsequent binding of a ph...
متن کاملAn ultrasensitive DNAzyme-based colorimetric strategy for nucleic acid detection.
An ultrasensitive DNAzyme-based colorimetric DNA detection strategy was developed by utilizing gold nanoparticles modified with both peroxidase-mimicking DNAzymes and capture DNAs and magnetic nanoparticles modified with another capture DNAs, with a detection limit for a model Chlamydia gene of 50 fM.
