ABSTRACT:
Disclosed is a method for production of recombinant human FSH in high yield and a high purity. The method comprises the steps of: (a) culturing recombinant human FSH-producing mammalian cells in a serum-free medium, (b) collecting culture supernatant, (c) subjecting the culture supernatant to cation-exchange column chromatography, (d) dye affinity column chromatography, (e) hydrophobic column chromatography, and (f) gel filtration column chromatography to collect recombinant human FSH-active fractions, in the order.
