  • Process for purifying proteins
    Patent number: 8273707
    Abstract: The invention relates to a process for purifying a protein by mixing a protein preparation with a solution having a first salt and a second salt, wherein each salt has a different lyotropic value, and loading the mixture onto a hydrophobic interaction chromatography column. The dynamic capacity of the column for a protein using the two salt combination will be increased compared with the dynamic capacity of the column for either single salt alone.
    Type: Grant
    Filed: June 23, 2010
    Date of Patent: September 25, 2012
    Assignee: Amgen Inc.
    Inventors: Anna Senczuk, Ralph Klinke
