Free and nonprotein amino acids of Tetrahymena pyriformis
(Elsevier, 1956-05)
Paper chromatography was used to determine 20 amino acids and related compounds present in both the free and the nonprotein forms in Tetrahymena pyriformis. The most abundant free amino acids in the cells were found to be ...
Effect of dinitrophenol on the interaction between myosin and nucleotides
(Elsevier, 1959-04)
1. 1. The effects of 2,4-dinitrophenol (DNP) on the interaction of several nucleoside triphosphates with myosin B and glycerol-treated psoas fibers have been studied at 0.3 M KCl, 10-3 M Ca++, pH 7.0, 25.5 [deg]C.2. 2. The ...
Glycolytic activity in extracts of young rat skin
(Elsevier, 1959-01)
1. 1. Data have been presented which indicate the presence of most of the glycolytic enzymes in the skin of the young rat.2. 2. A cell-free extract of this tissue will stoichiometrically convert fructose diphosphate to ...
Transduction and segregation in Escherichia coli K12
(Elsevier, 1957-10)
The transduction of the gal+ character into gal- mutants of Escherichia coli K12 with high frequency transducing (HFT) lysates of phage [lambda] has been studied. Sensitive recipients infected at low multiplicity give rise ...
Initial stages of the interaction of Hela cells with poliovirus
(Springer-Verlag, 1958-02)
Protection of workers against dermatitis on exposure to hydrazine hydrobromide soldering flux
(Springer-Verlag, 1955-01)
Physiology of the cell surface of Neurospora ascospores. II. Interference with dye adsorption by polymyxin
(Elsevier, 1956-05)
Polymyxin B prevents the germination of ascospores of Neurospora tetrasperma with an LD50 of 3-4 p.p.m. The toxic effect of polymyxin is partially reversed by calcium and magnesium ions. The effect of polymyxin on the ...
The metabolism of Brucellae: The oxidation of succinate as a function of pH and concentration
(Elsevier, 1956-10)
The marked difference between the rates of succinate uptake and oxidation by Brucella abortus that occurs when the concentration of hydrogen ions or the substrate is grossly increased was accounted for predominantly in ...
