  • Method for protection of proteolysis-susceptible protein during protein production in a fluid medium
    Patent number: 5623059
    Abstract: A process for the microbial production of a protein susceptible to inactivation in a fluid production medium by continuously and reversibly protecting said protein against said inactivation during the production stage, separating the protein from the production medium, deprotecting the protein, and recovering the protein product. The process is especially useful for obtaining substantially increased yields of the protein in question by continuously precipitating said protein.
    Type: Grant
    Filed: August 16, 1994
    Date of Patent: April 22, 1997
    Assignee: Novo Nordisk A/S
