Autoradiography with acrylamide gel slab electrophoresis
(Elsevier, 1969-04)
A method for electrophoresis and autoradiography with a multisample gel slab system has been described. The method obviates slicing of the gel, retains the high degree of resolution of bands in the autoradiogram, and enables ...
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 ...
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 ...
Studies of the electron transport systems of heart muscle: Biochemical and antigenic properties of a soluble DPNH dehydrogenase
(Elsevier, 1968-04)
Highly purified DPNH dehydrogenase has been prepared from preparations of DPNH oxidase. The enzyme has an average molecular weight of 80,000 and contains flavin, nonheme iron, and labile sulfide groups in an approximate ...
Two cases of changes in amino acid transport activity with tissue development
(Elsevier, 1965)
During the first day of extrauterine life the liver of the guinea-pig greatly intensifies the extent of the steady-state concentration of two amino acids, one normal and one non-metabolizable. Another change with tissue ...
Application of glass fiber chromatography for separation of C19 steroids
(Elsevier, 1968-12)
Protein-carbohydrate interaction : V. Further inhibition studies directed toward defining the stereochemical requirements of the reactive sites of concanavalin A
(Elsevier, 1967-07)
Inhibition studies on the concanavalin A-dextran interaction have been extended using as inhibitors the members of the maltose-, isomaltose-, and methyl [alpha]-isomaltoside series, amino and N-acetyl amino sugars, and a ...
The destruction of indoleacetic acid. III. Relationships between peroxidase action and indoleacetic acid oxidation
(Elsevier, 1960-03)
The indoleacetic acid (IAA)-oxidizing enzyme preparation from Omphalia flavida exhibits peroxidase activity on pyrogallol with an optimum at pH 3.5-3.7, like that for the IAA-oxidizing activity. It shows no polyphenolase ...
Reconstitution of oxidative phosphorylation in submitochondrial particles by a soluble protein phosphoryl transferase
(Elsevier, 1968-01)
A protein designated phosphoryl transferase has been isolated from beef heart mitochondria and has been found to increase the ability of Submitochondrial particles, oxidizing either NADH or succinate, to synthesize ATP ...
