Application of Gel Chromatography*
INTRODUCTION The term Gel Chromatography refers to the process of separation of solutes caused by the passage of a solution through a column filled with a porous gel. The dissolved particles may enter the pores fully or partially or they may remain completely excluded. This results in a sorting out of the dissolved particles according to their size, so that the largest particles migrate with th...
متن کاملGel-Filtration Chromatography.
Gel-filtration chromatography is a versatile method that permits the effective separation of biological molecules in high yield. This article describes the basis of the method, the selection of suitable operating conditions, and contrasts typical matrix types. Applications of the technique are described, with references to the scientific literature.
متن کاملpH-zone-refining countercurrent chromatography.
A recently developed preparative technique, pH-zone-refining countercurrent chromatography (CCC), separates organic acids and bases according to their pKa and hydrophobicity. The hydrodynamic mechanism of pH-zone-refining CCC is illustrated in two elution modes along with a simple mathematical analysis. Separations include acidic and basic derivatives of amino acids and peptides, hydroxyxanthen...
متن کاملFractionation of human urine by gel chromatography.
High-resolution anion-exchange chromatography of human urine can resolve more than 150 constituents that absorb ultraviolet light. Prefractionation of urine on Sephadex G.10 helped us identify the constituents and simplified the anion-exchange chromatogram. The material associated with the 13 peaks obtained by gel chromatography was pooled and concentrated into six fractions, which were subsequ...
متن کاملRefolding proteins by gel filtration chromatography.
We have developed a facile means for the refolding of milligram quantities of purified proteins that employs gel filtration chromatography. We demonstrate by electrophoretic mobility shift and NMR spectroscopy that human ETS-1 protein, bovine ribonuclease A and E. coli integration host factor can be refolded into the native conformation using this technique. We have extended this strategy to th...
