Process for preparing an alpha-1-antitrypsin solution
摘要:
A process for preparing A1AT from A1AT-containing solutions, comprising the following steps: (a) subjecting an A1AT-containing solution to ion-exchange chromatography; (b) adding detergents and optionally a solvent for inactivating lipid-enveloped viruses; (c) followed by increasing the salt concentration to salt out the detergents. A1AT having a purity of >90% with an activity of ≧0.8 PEU/mg in its active form.
