Resolving DNA Using A Bare Open Narrow Capillary without Sieving Matrix
(2014-08)
DNA molecules encode the hereditary information utilized in all living organisms, including humans. Separating DNA fragments is essential in biological research because it informs us how DNA molecules work and eventually ...
Development of procedures for the determination of catecholamines, indoleamines, related metabolites, and monoamine oxidase activity.
(1981)
A procedure was also employed for the determination of monoamine oxidase activity in tissue samples. Focusing on the analysis of the acidic metabolites of dopamine and/or 5-hydroxytryptamine, preincubation and incubation ...
Electrochemical and enzymatic oxidation of tryptophan and 7-methyluric acid ; and, spectroelectrochemical search for a tertiary alcohol intermediate in the electrochemical oxidation of uric acid /
(1985)
Part III describes the spectroelectrochemical evidence for the tertiary-alcohol intermediate formation during the electrochemical oxidation of uric acid. Electrochemical reduction of the tertiary-alcohol intermediate in ...
Characterization of pure and phase-stabilized sodium phosphate.
(1998)
This work illustrates the necessity of using a variety of techniques when characterizing these systems, which undergo complex structural changes that cannot be completely characterized using a single technique. The XRD ...
Investigation of matrix interferences in quantitative liquid chromatography-electrospray ionization mass spectrometry analysis of biological samples.
(2007)
The mechanisms by which endogenous GPCho lipids interfere with analyte electrospray ionization were investigated with the aid of a partition equilibrium mathematical model. A linear equation, which was derived by modifying ...
Applications of Button Sample Holders for Mid-Infrared Spectroscopy Measurements
(2021-12-17)
Infrared (IR) spectroscopy is a rapid and non-destructive method for chemical analysis that is based on interactions between electromagnetic radiation and matter. Despite its widespread popularity in commercial and research ...
Electrochemistry of methylated pterins :
(1982)
6,7-Dimethyl-5,6,7,8-tetrahydropterin (6,7-DMTHP) is an effective and widely used pseudo cofactor for phenylalanine hydroxylase in the hydroxylation reaction of phenylalanine. 6,7-DMTHP and other tetrahydropterins methylated ...
Development and application of spray-capillary, a novel device for microsampling, and online capillary zone electrophoresis mass spectrometry analysis on nanoscale omics study
(2021-12-17)
The capillary zone electrophoresis-mass spectrometry (CZE-MS) platform, a well-developed analytical methodology, has been widely used for high-throughput nanoscale (e.g., < 5000 cells, single-cell sample) bioanalysis (e.g., ...
