Ultraviolet-visible diode-array spectrophotometer as a detector for gas chromatography
(Elsevier, 1985-05-01)
An ultraviolet-visible diode-array spectrophotometer is used as a detector for gas chromatography. This detector can provide a full u.v.-visible spectrum of each compound as it elutes from the column, thus enhancing ...
Comparative proteomic study of two closely related ovarian endometrioid adenocarcinoma cell lines using cIEF fractionation and pathway analysis
(WILEY-VCH Verlag, 2009-04)
The proteomic profiles from two distinct ovarian endometrioid tumor-derived cell lines, (MDAH-2774 and TOV-112D) each with different morphological characteristics and genetic mutations, have been studied. Characterization ...
Supercritical fluid jet expansions of polar aromatic carboxylic acids using simple derivatization with detection by resonant two-photon ionization
(Elsevier, 1988)
In this work simple derivatization is used as a means of enhancing the solubility of polar aromatic carboxylic acids in supercritical CO2 and N2O. The supercritical fluid is then expanded from 200 atm and 40[deg]C through ...
Proteomic analysis of cold adaptation in a Siberian permafrost bacterium – Exiguobacterium sibiricum 255–15 by two-dimensional liquid separation coupled with mass spectrometry
(WILEY-VCH Verlag, 2006-10)
Bacterial cold adaptation in Exiguobacterium sibiricum 255–15 was studied on a proteomic scale using a 2-D liquid phase separation coupled with MS technology. Whole-cell lysates of E. sibiricum 255–15 grown at 4°C and ...
Excited state spectroscopy of para di-substituted benzenes in a supersonic beam using resonant two photon ionization
(Elsevier, 1986)
Excited state vibronic spectra of p-aminophenol, p-cresol, p-fluoroaniline, p-fluorophenol, hydroquinone and p-toluidine have been obtained using resonant two photon ionization supersonic beam mass spectrometry. Despite ...
Free-jet spectra and structure of o-, m- and p-dihydroxybenzenes
(Elsevier, 1985-11-15)
Analysis of the free-jet spectra of hydroquinone (para), catechol (ortho) and resorcinol (meta) shows the presence of multiple origins in each molecular spectrum which are interpreted as belonging to separate structural isomers.
The identification of phosphoglycerate kinase-1 and histone H4 autoantibodies in pancreatic cancer patient serum using a natural protein microarray
(WILEY-VCH Verlag, 2009-06)
Protein microarrays have been used to explore whether a humoral response to pancreatic cancer-specific tumor antigens has utility as a biomarker of pancreatic cancer. To determine if such arrays can be used to identify ...
Proteomic profiling identifies breast tumor metastasis-associated factors in an isogenic model
(WILEY-VCH Verlag, 2007-01)
A combination of LC and MS was applied to an isogenic breast tumor metastasis model to identify proteins associated with a cellular phenotype. Chromatofocusing followed by nonporous-RP-HPLC/ESI-TOF MS was applied to cell ...
Direct chemical analysis of UV laser ablation products of organic polymers by using selective ion monitoring mode in gas chromatography/mass spectrometry
(Elsevier, 1994-02)
Trace quantitites of laser ablated organic polymers were analyzed by using commercial capillary column gas chromatography / mass spectrometry; the instrument was modified so that the laser ablation products could be ...
The design and performance of an ion trap storage--reflectron time-of-flight mass spectrometer
(Elsevier, 1994-02-24)
The design and performance of an ion trap storage--reflectron time-of-flight mass spectrometer (IT--RETOF MS) combination have been explored for detection of ions generated from both internal and external ionization sources. ...
