Destruction of indoleacetic acid : IV. Kinetics of enzymic oxidation
(Elsevier, 1962-02)
Kinetics of enzymic oxidation of indoleacetic acid (IAA) are interpreted as indicating that the reaction has an autocatalytic, cyclical mechanism involving unstable intermediates whose formation and disappearance are ...
Microdetermination of dihydroxyacetone in biological fluids
(Elsevier, 1961-04)
Dihydroxyacetone is reacted with an excess of 2,4-dinitrophenylhydrazine. The excess reagent is removed by the addition of pyruvic acid and followed by partition between benzene and sodium bicarbonate solution. The benzene ...
Acute and short-term oral toxicity of 2-n-ethylaminoethanol in rats
(Elsevier, 1969)
Acute oral doses of neutralized 2-N-ethylaminoethanol (EAE) in rats greatly increased gastric secretion, resulting in dehydration and death after 3-4 days. The effect of EAE on gastric secretion did not appear to be due ...
Amino acid content of rabbit urine and plasma
(Elsevier, 1962-03)
The content of amino acids in plasma and urine from male albino rabbits was determined by ion-exchange chromatography and compared to values for other species.In general, the amino acids present in the plasma and urine of ...
Hapten-radioimmunoassay: A general procedure for the estimation of steroidal and other haptenic substances
(Elsevier, 1969-06)
Hapten-radioimmunoassay may be used for sensitive and specific quantitation of low molecular weight substances which can be made immunogenic by conjugation to a protein, This method, which involves radioiodination of the ...
Protein-carbohydrate interaction , : XVI. The interaction of concanavalin A with dextrans from L. mesenteroides B-512-F, L. mesenteroides (Birmingham), Streptococcus bovis, and a synthetic [alpha]-(1 --> 6)--glucan
(Elsevier, 1968)
The precipitation reaction between concanavalin A, the jack-bean hemagglutinin and several dextrans has been examined by means of the quantitative precipitin technique. A synthetic linear [alpha]-(1 --> 6)--glucan did ...
An anaerobic titration assembly for spectrophotometric use
(Elsevier, 1969-03)
An anaerobic titration apparatus capable of titrations of 2.5 ml of solution with microliter quantities of titrant is described. Numerous samples can be titrated with the same stock solution and back titrations with different ...
Identification of acid mucopolysaccharides by paper chromatography
(Elsevier, 1964)
A multiple solvent paper chromatography system is described which tentatively identifies most of the known mammalian acid mucopolysaccharides, when these are examined singly. Certain mucopolysaccharides may be identified ...
