Mixed ligand complexes of iron(ii) as nonaqueous acid-base and aqueous oxidation-reduction indicators
(Elsevier, 1962)
The neutral mixed ligand complexes dicyano-bis-(1,10-phenanthroline)-iron(II) and dicyano-bis-(2.2'-bipyridine)-iron(II) are suitable indicators for the titration of various weak bases in nonaqueous solvents, They also ...
Protein-carbohydrate interaction : III. Agar gel-diffusion studies on the interaction of concanavalin A, a lectin isolated from jack bean, with polysaccharides
(Elsevier, 1965-08)
Concanavalin A, a protein isolated from the jack bean (Canavalia ensiformis), has previously been shown to form a precipitate with glycogen and yeast mannan, and more recently with dextrans and amylopectin. Double-diffusion ...
On the nature of the "non-saturable" migration of amino acids into Ehrlich cells and into rat jejunum
(Elsevier, 1966-03-14)
The so-called non-saturable uptake of [alpha]-amino acids by the Ehrlich cell, even though it occurs at a characteristically slow rate for various neutral amino acids (whether they are in the - or the -form) is nevertheless ...
The constant-volume heat capacities of gaseous perfluorocyclobutane and propylene
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1960-03)
The constant-volume heat capacities of gaseous perfluorocyclobutane and propylene have been measured over a considerable range of temperatures and densities with a new type of adiabatic calorimeter. This calorimeter differs ...
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 ...
Starch-gel investigations of the relationships between dehydrogenase proteins
(Elsevier, 1967-09-12)
A band which migrates, during starch-gel electrophoresis, to a far cathodal position, and catalyzes the reduction of nitro blue tetrazolium without the addition of substrate, has previously been found to also be associated ...
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 ...
