Abstract
Disclosed is a highly efficient method for production of highly pure mutant-type human erythropoietin. The method is for production of mutant-type human erythropoietin, in which a transformed mammalian cell is allowed to produce the mutant-type human erythropoietin, and the supernatant of the culture is subjected to hydrophobic column chromatography, multimodal anion exchange column chromatography, anion exchange column chromatography, phosphate group affinity column chromatography, and gel filtration column chromatography, in this order.
