Adduct formation identification between phenyl glycidyl ether and 2'-deoxyadenosine and thymidine by chromatography, mass spectrometry and nuclear magnetic resonance spectroscopy
(Elsevier, 1990)
Thymidine 2'-deoxyadenosine were reacted with phenyl glycidyl ether in order to study the formation of the corresponding 2'-deoxynucleoside adducts. Separation methods were elaborated using either reversed-phase high-performance ...
Subcellular distribution of terminal α-D- and β-D-galactosyl residues in Ehrlich tumour cells studied by lectin-gold techniques
(Kluwer Academic Publishers; Chapman & Hall ; Springer Science+Business Media, 1995-04)
We have studied by high resolution in situ light and electron microscopic lectin-gold techniques the subcellular distribution of α- d -Gal residues using the Griffonia simplicifolia I-B 4 isolectin and compared it with ...
Potentiometric detection in ion chromatography using multi-ionophore membrane electrodes
(Elsevier, 1993-10-01)
The incorporation of ionophores selective for ammonium, potassium, sodium and calcium ions in an appropriate proportion into a plasticized poly(vinyl chloride) membrane provides a potentiometric membrane sensor with similar ...
Papaverine effects on PGI2 and TXA2 release from the canine vascular wall
(Elsevier, 1992-07)
Operative manipulation of blood vessels might lead to spasm, thereby destroying the endothelial cell function: the spasm can be prevented by the vasodilator papaverine. To study if this was mediated via the prostanoid ...
Purification and Characterization of a Mannose-Specific Lectin from Shallot (Allium ascalonicum) Bulbs
(Elsevier, 1993-11)
A new mannose-binding lectin was isolated from shallot (Allium ascalonicum) bulbs by affinity chromatography on an immobilized D-mannose column. The lectin (A. ascojonicum agglutinin, AAA) appeared homogeneous by polyacrylamide ...
Cultured Ehrlich Ascites Tumor Cells Show Increased N-Linked [alpha]2,6-Sialytransferase Activity
(Elsevier, 1993-06)
Ehrlich ascites tumor cells (EAT cells) are routinely grown in the peritoneal cavity of mice. These cells, EAT-wt, grow in suspension and exhibit a high level of [alpha]-2,3-O-linked sialyltransferase activity with ...
Association of the transformed glucocorticoid receptor with a cytoskeletal protein complex
(Elsevier, 1992-03)
In a recent paper we described a system in which glucocorticoid receptors associate with particulate complexes containing tubulin [Cancer Res. 49 (1989) 2222s-2229s]. When L cell cytosol is mixed with a microtubule stabilizing ...
Localization of the ~12 kDa Mr discrepancy in gel migration of the mouse glucocorticoid receptor to the major phosphorylated cyanogen bromide fragment in the transactivating domain
(Elsevier, 1993-12)
The intact wild-type mouse glucocorticoid receptor has a theoretical molecular weight of ~86 kDa based on amino acid sequence, but on SDS-polyacrylamide gel electrophoresis it migrates as a protein of ~98 kDa. It is not ...
