Iron-ethylenediaminetetraacetic acid (EDTA)-catalyzed superoxide dismutation revisited: An explanation of why the dismutase activity of Fe-EDTA cannot be detected in the cytochrome c/xanthine oxidase assay system
(Elsevier, 1982-05)
The recent assertion of [1.] that Fe-EDTA does not catalyze superoxide dismutation is disputed. By directly observing superoxide generated during pulse radiolysis, we have confirmed the results of a previous study ( [2.]) ...
Decreased pulmonary vascular responsiveness in rats raised on an essential fatty acid deficient diet
(Elsevier, 1987-02)
Leukotriene C4 is produced during hypoxic pulmonary vasoconstriction and leukotriene inhibitors preferentially inhibit the hypoxic pressor response in rats. If lipoxygenase products are important in hypoxic vasoconstriction, ...
Potentiometric study of cytochrome c1aa3 from thermus thermophilus
(Elsevier, 1985)
We have examined the redox behavior of the cytochrome c1aa3 complex from Thermus thermophilus. In potentiometric titrations the cytochrome c behaves as an independent center having n = 1 and E = 205 mV (NHE). Under the ...
Isolation and characterization of a second lectin (SNA-II) present in elderberry (Sambucus nigra L.) bark
(Elsevier, 1990-03)
A second lectin (SNA-II) has been isolated from elderberry (Sambucus nigra L.) bark by affinity chromatography on immobilized asialo-glycophorin. This lectin is a blood group nonspecific glycoprotein containing 7.8% ...
Rapid activation analysis of trace copper in tissue using 5.1-minute copper-66
(Elsevier, 1963-07)
Microgram amounts of copper have been analyzed by rapid activation analysis in rat kidney tissue. An 8-min radiochemical separation coupled with gamma-ray spectrometry permitted utilization of the 5.1-min copper-66 ...
Commentary: Landmark articles on copper in the field of human health
(John Wiley & Sons, Inc., 2001)
No abstract.
A quantitative dot-blot immunoassay for integral membrane proteins: Preparation of pancreatic plasma membranes containing apical and basolateral domains
(Elsevier, 1991-01)
Modifications of standard dot-blot immunoassay techniques have been made for the quantitation of integral membrane protein antigens. The modification involves the signal development step, which is performed by using ...
Development of a Universal Nucleobase and Modified Nucleobases for Expanding the Genetic Code
(W.H. Freeman and Co.Wiley Periodicals, Inc., 2002-09)
This unit presents protocols for the synthesis and characterization of nucleosides with unnatural bases in order to develop bases for the expansion of the genetic alphabet or for nonselective pairing opposite natural bases. ...
Purification and properties of trehalase(s) from Neurospora
(Elsevier, 1963-09)
Trehalase has been obtained in crystalline form from the mycelium of Neurospora crassa. During elution from the first pass through a DEAE-cellulose column, two peaks with trehalase activity were obtained. When the first ...
