S2.1 Structure and function of mammalian glycosyltransferase genes
(Kluwer Academic Publishers; Chapman & Hall ; Springer Science+Business Media, 1993-08)
Proteolytic and oxidoreductase activity of Treponema denticola ATCC 35405 grown in an aerobic and anaerobic gaseous environment
(Elsevier, 1993)
The cells of a human oral spirochetes. Treponema denticola ATCC 35405, and of seven clinical isolates of this organism obtained from the subgingival dental plaque of periodontitis] patients were studied for their ability ...
Characterization of pro-opiomelanocortin processing in heterologous neuronal cells that express PC2 mRNA
(Elsevier, 1993-05)
We have investigated processing of monkey pro-opiomelanocortin (POMC) following transfection into heterologous neuronal Neuro 2A (N2A) cells. In several separately transfected stable cell lines (termed N2A/POMC2-like; N = ...
Conformational studies of hairpin sequences from the ColE1 cruciform
(Elsevier, 1993)
Inverted repeat sequences derived from the ColE1 cruciform were investigated by nuclear magnetic resonance (NMR) and UV spectroscopy. It was shown that 15 different sequences exist as stable hairpin structures over a range ...
Systematic approach to the development of plasma amino acid analysis by high-performance liquid chromatography with ultraviolet detection with precolumn derivatization using phenyl isothiocyanate
(Elsevier, 1993-11-17)
A reversed-phase liquid chromatographic method for the separation of 26 phenylthiocarbamyl derivatives of amino acids in human plasma in ca. 35 min. is described. The method used a C18 column (150 x 4.6 mm I.D., 3 [mu]m) ...
Hydrogen Peroxide-Dependent Formation and Bleaching of the Higher Oxidation States of Bovine Erythrocyte Green Hemeprotein
(Elsevier, 1993-02-15)
The ferric and ferrous forms of bovine erythrocyte green hemeprotein react with hydroperoxides to form higher oxidation state intermediates with absorbance maxima in the Soret region at 426 and 422 nm, respectively. In the ...
Defined Analyte-Enzyme Conjugates as Signal Generators in Immunoassays
(Elsevier, 1993-04)
We investigated the synthesis of progesterone-horseradish peroxidase (P-HRP) conjugates and products purified by affinity chromatography. The obtained preparations were characterized with an immobilized monoclonal antibody ...
Junctional diversification in the generation of the precursor of a discrete immune response
(Elsevier, 1993-03)
Phosphocholine (PC)-specific antibodies that arise in the mouse in response to Proteus morganii (PM) and use V1-DFL16.1-JH1 are characterized by a number of recurring mutations. Most striking is an invariant A for G ...
An Anti-CD2 Monoclonal Antibody That Both Inhibits and Stimulates T Cell Activation Recognizes a Subregion of CD2 Distinct from Known Ligand-Binding Sites
(Elsevier, 1993-09)
The T lymphocyte glycoprotein CD2 appears to have an important role in human T cell development and activation. A novel anti-CD2 monoclonal antibody, designated UMCD2, was shown to block E rosetting, and therefore was ...
