    摘要: The invention concerns a method for purifying G-CSF from a biological sample comprising steps which consist in: a) reducing the volume of the biological sample containing the G-CSF by hydrophobic interaction chromatography to obtain a concentrated, desalted and enriched fraction; b) passing the concentrated fraction over hydroxyapatite in conditions whereby the G-CSF is slightly bound to obtain a concentrated, desalted and enriched fraction containing the G-CSF; and c) collecting the G-CSF.
