Citrate, sulphate, oxalate, chromate, carbonate, fluoride, acetate, formate, iodate, bicarbonate, bromate, chloride, nitrite, chlorate, bromide, nitrate, iodide, perchlorate and thiocyanate (each with sodium as counter-ion) were applied to a column of Sephadex G-15, and elution was carried out w...detailed
When a sample solution containing sodium-22-labelled sodium chloride and carrier-free phosphorus-32-labelled phosphoric acid was eluted from a Sephadex G-15 column with either 0.025 M sodium or potassium phosphate buffer (pH 7.0), the labelled phosphate ion was eluted earlier than the sodium-22....detailed
When a mixed solution of 0.72 M potassium and sodium chloride was eluted from a Sephadex G-15 column with 0.025 M sodium phosphate buffer (pH 7.0), the elution profiles of ions showed that the potassium and chloride ion pair from the sample and the sodium and chloride ion pair produced by ion-ex...detailed
There is good evidence that, in Sephadex gels, oligosaccharide series how (positive) linear free energy relations with respect to the degree of polymerisation. The distribution coefficients of disaccharides are thus a measure of the differences between the polyglucan series to which they belong....detailed
When a mixed solution of sodium or potassium dihydrogenphosphate and disodium or dipotassium hydrogenphosphate was eluted from a Sephadex G-15 column with either a sodium or potassium chloride solution, the elution profiles of ions showed that the hydrogenphosphate ion was eluted more rapidly th...detailed
Semen from five dairy AI bulls was split-filtered through a Sephadex G-15 filter and frozen in a Tris–citric acid buffer egg yolk-based extender. The effect of filtration was studied morphologically for individual sperm abnormalities. Computer-assisted sperm analysis (CASA) was used for motilit...detailed
Gel chromatography of the humic substances in coexisting inorganic salts using untreated and ammonia-treated Sephadex G-15 was investigated. The fulvic acid found in treated sewage and the fulvic and humic acids found in leaf mold were used as samples.When untreated Sephadex G-15 was used, the e...detailed
