Abstract
The invention provides a novel process for the production of erythropoietin, which is a promising medicine for curing anemia, from human urine containing the same. The inventive method comprises adjusting the pH value of the urine in the range from 6 to 8, if the pH value of the urine is out of this range, and contacting the thus pH-controlled urine with a specific adsorbent so as that the erythropoietin is selectively adsorbed on the adsorbent. The adsorbed erythropoietin is then eluted out by use of an eluant solution to give the product in a partially purified form.
