Preparative isolation of amino acids by carrier displacement chromatography on ion exchange resins.
Chromatographic separations of amino acids on ion exchange resins may be performed on a preparative scale either by elution (24) or by displacement (5-12). Some of the exceptional resolving power demonstrated in analytical separations by elution techniques (13, 14) disappears when larger columns with relatively higher loads are used (2). Displacement chromatography allows large quantities of so...

متن کاملDisplacement Chromatography on Synthetic Ion - exchange Resins
In Part 1 of this series of papers (Partridge & Westall, 1949) it was shown that, whilst the baseexchange resin Zeo Karb 215 may be used with success for the separation of the neutral and acidic amino-acids, certain difficulties arise when the separation of basic substances is attempted. These difficulties were traced to the phenolic hydroxyl groups of the resin. Resins of the sulphonated pheno...
متن کاملUltrafiltration and Displacement Chromatography
Although apparently the first effective parathyroid extract was prepared by Moussu in 1898, some time elapsed before Hanson (1926) and Collip (1925) clearly demonstrated that an active extract of consistent potency could be prepared by using hot dilute hydrochloric acid. Since that time there have been a number of attempts to purify such extracts further. Some further purification was achieved ...
متن کاملA note on the paper chromatography of hemoglobins.
T WAS RECENTLY CLAIMED (1) that by paper chromatographic methods the hemoglobins prepared from a variety of human bloods-of normal adults, of the umbilical cord, and of subjects with sickle-cell anemia or Mediterranean anemia-could each be resolved into a number of molecular species. The methods employed involved the use, as solvents, of aqueous solutions of sucrose and salts, of pyridine and o...
