Beschreibung
Zusammenfassung:	The invention discloses a method for purifying a human urinary trypsin inhibitor (hUTI). The method comprises the following steps that: a, a solution containing the urinary trypsin inhibitor and cation exchange resin are contacted, so that the urinary trypsin inhibitor is adsorbed on the cation exchange resin; and b, a pH1-7 buffering liquid is used to elute the urinary trypsin inhibitor adsorbed on the cation exchange resin to obtain purified urinary trypsin inhibitor. The method is simple and high-efficient; and an obtained product has high purity.
