Zonal density gradient electrophoresis of intracellular membranes of brain cortex
(Elsevier, 1969-03-11)
Rat cerebral cortex was homogenized in a sucrose-free medium and a number of intracellular membrane fractions were isolated therefrom by means of differential and density-gradient centrifugation. The mitochondrial and ...
The action of trypsin and neuraminidase on the synaptic membranes of brain cortex
(Elsevier, 1969-03-11)
The population of intracellular membranes of rat cerebral cortex which exhibited the highest relative specific concentration of bound N-acetylneuraminic acid (NANA) and the highest relative specific activity of ...
Rhenium and technetium (VI) and meso-(VII) species
(Elsevier, 1969-01)
Spectrophotometric study shows that less than 35 per cent of normal perrhenate converts to a meso form in 15 M base, and Kf ~ 0[middle dot]1. The species absrobs at 260 m[mu] ([epsilon] = 6,400) and near 310 m[mu] ([epsilon] ...
Protein---carbohydrate interaction : Part XXI. The interaction of concanavalin a with d-fructans
(Elsevier, 1969-06)
The immunochemical techniques of quantitative precipitation and hapten inhibition have been employed in a study of the interaction of concanavalin A with several levans of bacterial and plant origin. Of the polysaccharides ...
Electrochemical oxidation-reduction paths for pyrimidine, cytosine, purine and adenine : Correlation and application
(Elsevier, 1969-07)
In order to evaluate the striking discrepancy between the experimental ease of polarographic reduction of adenine and cytosine, and that predicted by molecular orbital calculation, the electrochemical oxidation-reduction ...
Matrix elements for configuration d4s in a weak octahedral field using Racah methods
(Elsevier, 1969-07)
The general formula for matrix elements of configuration d4s in a weak crystalline field have been derived by means of Racah algebra. These have been explicitly applied to the case of d4s. The tabulated reduced matrix ...
Influence of counterions on the helical conformations of charged polypeptide chains
(Wiley Subscription Services, Inc., A Wiley Company, 1969-11)
No Abstract.
A new, sensitive determination of phosphate
(Elsevier, 1969-07)
A new method for the determination of phosphorus using Triton X-100 instead of reducing agents is more sensitive than procedures described earlier. Organic phosphate esters do not appear to interfere with the determination ...
