Purified .alpha.1-acid glycoprotein and a process for preparing purified .alpha.1-acid glycoprotein. The process comprises providing an impure protein fraction, binding contaminants, but not .alpha.1-acid glycoprotein, to a cation-exchange medium, and binding .alpha.1-acid glycoprotein to a anion-exchange medium, and eluting the .alpha.1-acid glycoprotein from the anion-exchange medium.
Cette invention concerne une glycoprotéine 'alpha'1-acide purifiée et un procédé de préparation de cette dernière selon lequel on place une fraction de protéine unique, des contaminants de liaison, mais pas une glycoprotéine 'alpha'1-acide, dans un milieu échangeur de cations, on lie la glycoprotéine 'alpha'1-acide avec un milieu échangeur d'anions, puis on élue la glycoprotéine 'alpha'1-acide du milieu échangeur d'anions.
