Proteomic analysis of estrogen response of premalignant human breast cells using a 2-D liquid separation/mass mapping technique
(WILEY-VCH Verlag, 2006-07)
A 2-D liquid-phase separation method based on chromatofocusing and nonporous silica RP-HPLC followed by ESI-TOF-MS was used to analyze proteins in whole cell lysates from estrogen-treated and untreated premalignant, ...
[omega]-1 and [omega]-2 hydroxylation of prostaglandins by rabbit hepatic microsomal cytochrome P-450 isozyme 6
(Elsevier, 1985-11-15)
Incubation of prostaglandin E1 (PGE1) with liver microsomes from control rabbits and from rabbits treated with ethanol or imidazole yielded 18-, 19-, and 20-hydroxy metabolites, representing hydroxylation at [omega]-2, ...
Selective catechol oxidations with diphenyl selenoxide. Applications to phenolic coupling.
(Elsevier, 1979)
Diphenyl selenoxide was used as a mild and selective oxidant in the synthesis of aporphines and homoaporphines. An intramolecular coupling between a phenol and a catechol is believed to proceed catechol selenurane intermediates.
Specific steroid response from a nonspecific DNA element
(Elsevier, 1994-06)
A fundamental dilemma of steroid hormone regulation is how specific transcription is attained in vivo when several receptors recognize the same DNA sequence in vitro. We have identified an enhancer of the mouse sex-limited ...
Immunochemical studies of the combining sites of the two isolectins, A4 and B4, isolated from Bandeiraea simplicifolia
(Elsevier, 1979-11)
The specificity of two isolectins, A4 and B4, of Bandeiraea simplicifolia lectin I (BS-I) was studied by quantitative precipitin, precipitin inhibition, as well as by competitive binding assays using various blood group ...
Enzymatic synthesis of sialyl Lex and derivatives based on a recombinant fucosyltransferase
(Elsevier, 1991)
A recombinant human Lewis [alpha](1,3/1,4)fucosyltranferase has been studied for its acceptor substrate specificity and used in the synthesis of sialyl Lex and derivatives.
Effect of fixation temperature on flow cytometric measurement of intracellular antibody content of hybridomas during batch culture
(Kluwer Academic Publishers; Science & Technology Letters ; Springer Science+Business Media, 1993-04)
In order to investigate the effect of fixation temperature on flow cytometric measurement of intracellular antibody content of hybridoma cells, cells in different growth stages during a batch culture were fixed and stored ...
Adrenal proteins bound by a reactive intermediate of mitotane
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-02)
Purpose : Mitotane ( o,p ′-DDD), is the only adrenolytic agent available for the treatment of adrenocortical carcinoma. Previous studies have shown that mitotane covalently binds to adrenal proteins following its metabolism ...
Oxidation of 2-keto-4-hydroxyglutarate by pig heart and Escherichia coli [alpha]-ketoglutarate dehydrogenase complex
(Elsevier, 1979-01)
Enzyme preparations from pig heart and Escherichia coli have been found to catalyze a NAD+- and CoASH-dependent oxidation of 2-keto-4-hydroxyglutarate. Several independent lines of evidence indicate that 2-keto-4-hydroxyglutarate ...
