  • Method for producing a preparation based on fibrinogen and fibronectin as well as protein compositions obtainable according to this method
    Patent number: 7241603
    Abstract: A method for producing protein compositions comprising fibrinogen and fibronectin is disclosed, wherein a fibrinogen and fibronectin-containing starting solution is treated with a precipitating composition which comprises two different components that modify the solubility of fibrinogen and/or fibronectin, so that in a single-step precipitation a precipitate is formed which comprises fibrinogen and fibronectin, and the precipitate formed optionally is further treated by methods known per se.
    Type: Grant
    Filed: November 19, 2002
    Date of Patent: July 10, 2007
    Assignee: Baxter Aktiengesellschaft
    Inventors: Thomas Seelich, Ralf Broermann
  • Method for producing fibronectin and fibrinogen compositions using a polyalkylene glycol and glycine or &bgr;-alanine
    Patent number: 6579537
    Abstract: A method of producing a pharmaceutical preparation comprising fibronectin and fibrinogen is disclosed. The method involves admixing into a starting solution of fibrinogen and fibronectin, in a single step, a precipitating composition comprising a polyalkylene glycol and at least one of glycine and &bgr;-alanine which forms a precipitate. Next, the precipitate is collected and a pharmaceutical preparation is prepared from the precipitate. The pharmaceutical preparation has a fibronectin:fibrinogen ratio from about 0.02 to about 0.2.
