Abstract
Method for obtaining highly purified transferrin from a partially purified plasma fraction containing transferrin in which the starting fraction is concentrated. Its ionic strength is reduced and then transferrin is adsorbed onto a chromatographic column. Following elution, the transferrin can be further processed through to packaging in final containers. The final purified transferrin product is sterile, at least 95% pure and is substantially free of enveloped and non-enveloped viruses.
