  • Process for purifying a polymer mixture
    Patent number: 9617313
    Abstract: A process of purifying copolymer peptides such as COP-1 polypeptides by ultrafiltration can be improved by treating the polypeptide solution with an acid before, or during the early stages of, the ultrafiltration. By adding the acid and/or forming an acid addition salts of the polypeptide before ultrafiltration is conducted permits for faster ultrafiltration. Likewise, adding the acid in the ultrafiltration process but before polypeptide precipitation or clogging occurs can also improve the efficiency/convenience of the ultrafiltration step.
    Type: Grant
