Nuclear phosphoproteins : I. Isolation and characterization of a phosphoprotein fraction from calf thymus nuclei
(Elsevier, 1969-02-04)
A phosphoprotein fraction has been isolated from calf thymus nuclei which contains about 1.3% alkali-labile phosphorus by wt. The enzymatic reaction in which serine and threonine residues in the protein are phosphorylated ...
Phosphoproteins from calf-thymus nuclei: Studies on the method of isolation
(Elsevier, 1969-11-11)
Erythrocyte metabolism and function: Hexokinase inhibition by 2,3-diphosphoglycerate and interaction with ATP and Mg2+
(Elsevier, 1969-11-18)
Recent findings have suggested an important role for variation in levels of 2,3-diphosphoglycerate and ATP in the regulation of oxygen transport by the human erythrocyte, and in making homeostatic adjustments to hypoxia. ...
The emission of K-X-rays in slow neutron fission of 233U, 235U, and 239Pu
(Elsevier, 1969-10)
Infrared internal reflectance spectroscopic determination of surface functional groups on carbon
(Elsevier, 1969-09)
An internal reflectance spectrophotometric technique for the direct study of the infrared spectrum of surface functional groups on carbon is presented. The applicability and limitations of this technique are discussed. The ...
Na+ and K+ electrochemical potential gradients and the transport of [alpha]-aminoisobutyric acid in Ehrlich ascites tumor cells
(Elsevier, 1969-11-25)
1. 1. The uptake of [alpha]-aminoisobutyric acid (AIB) was measured in Ehrlich ascites tumor cells which were treated by osmotic shock and cold incubation to elevate cell Na+ and lower K+. These cells were suspended in ...
Analysis of the volatile combustion products of vinyl plastics
(Wiley Subscription Services, Inc., A Wiley Company, 1969-02)
The extensive use of plastics for insulation and building materials has created interest in the possible toxicity of their combustion products. Three poly(vinyl chloride) homopolymers, a vinyl chloride-vinyl acetate ...
Solubilization of water by dialkyl sodium sulfosuccinates in hydrocarbon solutions
(Elsevier, 1969-01)
The apparent solubilization of water in hydrocarbon solvents by the addition of 0.1% to 2.0% w/w di-(2-ethylhexyl) sodium sulfosuccinate (AOT) has been studied. In n-octane and n-decane, transitions of clear-turbid-clear-turbid ...
Circular dichroism of the “random” polypeptide chain
(Wiley Subscription Services, Inc., A Wiley Company, 1969-09)
The circular dichroism (CD) spectrum of an unordered polypeptide chain does not correspond, as has been assumed heretofore, to that of a charged chain such as poly- L -glutamic acid or poly- L -lysine. The latter have been ...
