Rapid separation and sensitive determination of banned aromatic amines with plastic microchip electrophoresis.
Rapid analysis of trace amount of aromatic amines in environmental samples and daily necessities has attracted considerable attentions because some of them are strongly toxic and carcinogenic. In this...Read More
Chiral separation of β-blockers by MEEKC using neutral microemulsion: Analysis of separation mechanism and further elucidation of resolution equation.
Based on the investigation of the effect of microemulsion charge on the chiral separation, a new chiral separation method with MEEKC employing neutral microemulsion was established. The method used a ...Read More
Separation and determination of B vitamins and essential amino acids in health drinks by CE-LIF with simultaneous derivatization.
An efficient and sensitive method for the separation and determination of three essential amino acids and three B vitamins by CE-LIF with a simultaneous derivatization procedure was developed. The con...Read More
The molecular structure of the sodium borate mineral ameghinite NaB(3)O(3)(OH)(4) has been determined by the use of vibrational spectroscopy. The crystal structure consists of isolated [B(3)O(3)(OH)(4...Read More
Field enhancement sample stacking for analysis of organic acids in traditional Chinese medicine by capillary electrophoresis.
A technique known as field enhancement sample stacking (FESS) and capillary electrophoresis (CE) separation has been developed to analyze and detect organic acids in the three traditional Chinese medi...Read More
Effect of sugar additives on stability of human serum albumin during vacuum foam drying and storage.
No literature on the protein stabilization of human serum albumin (HSA) by vacuum foam drying (VFD) has been reported. The purpose of this study was to investigate the effect of sugar-additive systems...Read More
High-sensitivity capillary electrophoresis method for monitoring purine nucleoside phosphorylase and adenosine deaminase reactions by a reversed electrode polarity switching mode.
A simple, efficient, and highly sensitive in-line CE method was developed for the characterization and for inhibition studies of the nucleoside-metabolizing enzymes purine nucleoside phosphorylase (PN...Read More
Antifungal efficacy of environmentally friendly wood preservatives formulated with enzymatic-hydrolyzed okara, copper, or boron salts.
Okara, an organic waste product obtained from soy milk production, was used with copper chloride or sodium borate to formulate new wood preservatives as a substitute for expensive wood preservatives, ...Read More
Analysis of glycated hemoglobin A1c by capillary electrophoresis and capillary isoelectric focusing.
Two capillary electrophoretic methods were developed and evaluated for measurement of glycated hemoglobin A1c (HbA1c). First, a capillary electrophoresis analysis is performed with a sodium tetraborat...Read More
Selective deuterium labeling of the sphingoid backbone: facile syntheses of 3,4,5-trideuterio-d-erythro-sphingosine and 3-deuterio-d-erythro-sphingomyelin.
Deuteration at C-4 and C-5 of sphingosine was achieved via a hydrogen-deuterium exchange reaction of a β-ketophosphonate intermediate catalyzed by ND?Cl in D?O/tetrahydrofuran. To install deuterium a...Read More
MMP-28 (epilysin) is a recently cloned member of the MMP (matrix metalloproteinase) family. It is highly expressed in the skin by keratinocytes, the developing and regenerating nervous system and a nu...Read More
Analysis of supercoiled DNA by agarose gel electrophoresis using low-conducting sodium threonine medium
We describe a new low-ionic-strength sodium threonine (STh) medium with the advantage of avoiding relative DNA band migration changes following electrophoresis of supercoiled DNA in agarose gel when s...Read More
