Abstract

Abstract Translated from French La présente invention concerne un procédé de production d'érythropoïétine purifiée à partir d'urine humaine. Selon l'invention, ledit procédé comprend les étapes de : a. ajuster le pH de l'urine dans un domaine compris entre 6 et 8, si le pH de l'urine est en dehors de ce domaine, b. mettre en contact l'urine ayant un pH ainsi contrôlé avec un adsorbant sélectionné dans le groupe comprenant une résine adsorbante poreuse à base de polystyrène, le chitosane et la terre à diatomées, pour ainsi adsorber l'érythropoïétine sur ledit adsorbant, c. séparer ledit adsorbant ayant adsorbé l'érythropoïétine de l'urine traitée, et d. éluer l'érythropoïétine dudit adsorbant. L'invention s'applique dans le domaine médical. The present invention relates to a method of producing purified erythropoietin from human urine. According to the invention, said method comprises the steps of: a. adjust the pH of the urine to a range between 6 and 8, if the pH of the urine is outside this range, b. contacting urine having a pH thus controlled with an adsorbent selected from the group consisting of a porous adsorbent resin based on polystyrene, chitosan and diatomaceous earth, thereby adsorbing erythropoietin on said adsorbent, c. separating said adsorbent having adsorbed erythropoietin from the treated urine, and d. eluting erythropoietin from said adsorbent.
