Chromatographic separation of alkaline earth metals using alpha-hydroxyisobutyric acid

Creator:: Hauschild, John Arthur
Abstract:: A systematic study of the elution of magnesium and calcium from Dowex 50 X 8 resin using α-hydroxyisobutyric acid (α-HIBA) at various pH values and concentrations, indicated that the difference in the equilibrium distribution coefficients of these two elements was large enough for a good separation. This fact was applied...

Mass spectrometric analysis of proteins and peptides : elucidation of the folding pathways of recombinant human macrophage colony stimulating factor beta

Creator:: Zhang, Yuan Heidi
Abstract:: Recombinant human macrophage colony stimulating factor beta (rhm-CSFβ) is a glycoprotein that stimulates the proliferation, differentiation and survival of cells belonging to the monocyte-macrophage lineage. It contains nine inter-subunit and intra-subunit disulfide bonds and represents an excellent model system for studying disulfide bond formation during protein folding because the assembly...

Mass spectrometric studies on peptides and proteins : conformations of Escherichia coli Thioredoxin and its alkylated adducts studied by hydrogen/deuterium exchange and HPLC-electrospray ionization mass spectrometry

Creator:: Kim, Moo-young
Abstract:: E. coli thioredoxin (TRX) was modified by the episulfonium ion derived from S-(2-chloroethyl)glutathione (CEG) or S-(2-chloroethyl)cysteine (CEC). The alkylation site was located at Cys-32, which was confirmed by tandem mass spectrometry. Two forms of native TRX, Oxi- and Red-TRX, and two modified TRXs, GS- and Cys-TRX, were examined by hydrogen/deuterium...

An investigation of the absorption spectra of EGTA metal complexes and the development of spectrophotometric methods for the analyses of copper, erbium, europium, holmium, neodymium, and praseodymium

Creator:: Holmes, Ivan Gregory
Abstract:: The reactions of EGTA, [ethylene bis (oxyethylenenitrilo)] tetraacetic acid, with 51 metal ions have been studied spectrophotometrically in aqueous solutions. The absorption spectra of the chelates formed were measured with a recording spectrophotometer between 200 and 700 mμ. The pH of each solution was varied and a spectrum was scanned...

Synthesis of furanoeremophilane sesquiterpenoids

Creator:: Shanmugham, Meenakshi Sundaram
Abstract:: Two approaches to the tricyclic core of the furanoeremophilane sesquiterpenoids are described. The first approach entails a projected Diels-Alder/retro Diels-Alder reaction of an acetylenic oxazole 64. Construction of the pivotal aldehyde 67 commenced from ketone 68. The acetyenic moiety was then introduced via a Felkin-Ahn addition of lithiopropyne to aldehyde...

Design, construction, and characterization of a six-electrode, direct current, variable length plasma source for atomic emmission spectroscopy

Creator:: Shields, James Phillip
Abstract:: The variable length, six-electrode plasma source for atomic emission spectroscopy described here is operated from three compact, simple, and inexpensive direct current power supplies. The vertical arcs formed between the three electrode pairs completely entrain the sample and are typically operated at 40 V and 20 A. Three concentric quartz...

Selective detection for gas chromatography by ultraviolet spectrometry

Creator:: Van Engelen, Debra L.
Abstract:: Spectrometric detection systems for gas chromatography (GC) based on gas phase ultraviolet absorbance and fluorescence measurements have been developed and evaluated in this research. Polynuclear aromatic compounds (PNAs) are selectively detected by these systems. Limits of detection for PNAs range from 4 ng to 90 ng for absorbance determinations, and...
