Physicochemical and immunochemical studies on the reaction of bovine serum albumin with p,p'-difluoro-m,m'-dinitrodiphenylsulfone
(Elsevier, 1963-02)
Bovine serum albumin (BSA) was reacted with the bifunctional reagent p,p'-difluoro-m,m'-dinitrodiphenylsulfone (FNPS) under varying conditions. While intramolecular cross linkages involving the lysine and tyrosine residues ...
The photometric estimation of luciferase in luminous bacterial cells
(Elsevier, 1963-05)
The bacterial luciferase reaction carried out in vitro can be used as a basis for a semiquantitative assay of active luciferase in bacterial cells. Relations between maximum luminous intensity generated and the amount of ...
Solution and bulk properties of branched polyvinyl acetates : Part I: Non-Newtonian viscosity behaviour
(Elsevier, 1963)
A series of linear and branched fractions of polyvinyl acetate of relatively narrow molecular weight distribution was prepared and characterized by solution viscosity, hydrolysis, and light scattering measurements. At a ...
Hydrocarbon oxidation by a bacterial enzyme system : I. Products of octane oxidation
(Elsevier, 1963)
A Pseudomonad which grows on hexane as sole carbon source was isolated from soil by enrichment-culture technique. Cell-free, soluble enzyme preparations of the organism catalyze the oxidation of 14C-labeled octane to ...
The enzymic synthesis of the sulfate esters of estradiol-17[beta] and diethylstilbesterol
(Elsevier, 1963)
The present study demonstrates the formation of three sulfate esters of estradiol and three of diethylstilbesterol by a microsome-free extract of rat liver.The sulfate esters were separated by paper chromatography using a ...
Determination of small amounts of zirconium--I: gravimetric procedures using mandelic acid and its derivatives
(Elsevier, 1963-06)
The limiting factors have been investigated for precipitation of zirconium at the milligram level by mandelic acid, p-bromomandelic acid and m-nitromandelic acid; the latter has only been briefly studied previously. Optimum ...
Starch-gel electrophoresis of citrate-condensing enzyme from pig heart
(Elsevier, 1963)
Citrate-condensing enzyme from pig heart can exist in vitro as two distinct species which are separable by starch-gel electrophoresis. Several mild types of treatment can interconvert these enzymes and suggest that the ...
