Patent

CA 2479355

There is provided a method for the purification of bio-molecules after chemical modification using one or more insoluble polymer supported reagents. More particularly, the present invention provides a method for the fast purification of labeled bio-molecules using insoluble polymer supported quenching reagents. There are also provided novel polymer supported reagents of the formula (I): Rs-Sp-Re, wherein Rs is an insoluble polymer, Re is one or more reagent residues and Sp is one or more chemically robust spacer that join Rs and Re; and a process for their preparation.

La présente invention concerne un procédé pour la purification de molécules biologiques après modification chimique en utilisant un ou plusieurs réactifs supportés par des polymères. La présente invention concerne plus particulièrement un procédé pour la purification rapide de molécules biologiques marquées en utilisant des réactifs d'extinction supportés sur des polymères insolubles. L'invention concerne également de nouveaux réactifs supportés par des polymères représentés par la formulé suivante (I): Rs-Sp-Re, dans laquelle Rs est un polymère insoluble, Re est un ou plusieurs groupes fonctionnels du réactif, et Sp est un ou plusieurs intercalaires chimiquement cohérents qui réunissent Rs et Re. L'invention concerne enfin un procédé pour leur préparation.
